NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)

July 1, 2018

Note 1. General

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements have been prepared by Teledyne Technologies Incorporated (“Teledyne” or the “Company”) pursuant to the rules and regulations of the Securities and Exchange Commission. Certain information and disclosures normally included in notes to consolidated financial statements have been condensed or omitted pursuant to such rules and regulations, but resultant disclosures are in accordance with accounting principles generally accepted in the United States (“GAAP”) as they apply to interim reporting. The condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and the related notes in Teledyne’s Annual Report on Form 10-K for the fiscal year ended December 31, 2017 (“2017 Form 10-K”).

In the opinion of Teledyne’s management, the accompanying unaudited condensed consolidated financial statements contain all adjustments (consisting of normal recurring adjustments) necessary to present fairly, in all material respects, Teledyne’s consolidated financial position as of July 1, 2018 and the consolidated results of operations, consolidated comprehensive income or the three and six months then ended and cash flows for the six months then ended. The results of operations and cash flows for the period ended July 1, 2018 are not necessarily indicative of the results of operations or cash flows to be expected for any subsequent quarter or the full fiscal year. Certain prior year amounts have been reclassified to conform to the current period presentation.

In the second quarter of 2018, we realigned the reporting structure for certain of our microwave product groupings. These products, acquired with the acquisition of e2v were formerly reported as part of the Aerospace and Defense Electronics segment and are now reported as part of the Digital Imaging segment. Previously reported segment data has been adjusted to reflect this change. Total sales for these products were $24.2 million for fiscal year 2017.

Recent Accounting Pronouncements

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). The new guidance will require lessees to recognize most leases on their balance sheet as a right-of-use asset and a lease liability, other than leases that meet the definition of a short-term lease. For income statement purposes, the FASB retained a dual model, requiring leases to be classified as either operating or finance. The new guidance is effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years, with early adoption permitted. The new guidance can be adopted using either a modified retrospective transition, requiring application at the beginning of the earliest comparative period presented or a transition method whereby companies could continue to apply existing lease guidance during the comparative periods and apply the new lease requirements through a cumulative-effect adjustment in the period of adoption rather than in the earliest period presented without adjusting historical financial statements. We plan to adopt the new standard on December 31, 2018, the beginning of our 2019 fiscal year, and are currently evaluating the impact this guidance will have on the consolidated financial statements, including the selection of a transition method, and footnote disclosures. Please refer to Note 13 of the Notes to Consolidated Financial Statements included in our 2017 Form 10-K for additional information about the Company’s leases, including the future minimum lease payments of the Company’s operating leases at December 31, 2017.

In February 2018, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2018-02, “Income Statement-Reporting Comprehensive Income (Topic 220) Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income”, to address a specific consequence of the Tax Cuts and Jobs Act (“Tax Act”) by allowing a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Act reduction of the U.S. federal corporate income tax rate.  The guidance is effective for all entities for annual periods beginning after December 15, 2018, with early adoption permitted, and is to be applied either in the period of adoption or retrospectively to each period in which the effect of the change in the U.S. federal corporate income tax rate in the Tax Act is recognized.   Teledyne is currently evaluating the impact this guidance will have on the consolidated financial statements and footnote disclosures.

In August 2017, the FASB issued ASU No. 2017-12, “Derivatives and Hedging (Topic 815) Targeted Improvements to Accounting for Hedging Activities.” This ASU better aligns an entity’s risk management activities and financial reporting for hedging relationships. This ASU expands and refines hedge accounting for both nonfinancial and financial risk components, and this ASU simplifies and aligns the recognition and presentation of the effects of the hedging instrument and the hedged item in the financial statements. This ASU is effective for fiscal years beginning after December 15, 2018 and for interim periods therein, with early adoption permitted. Teledyne is currently evaluating the impact this guidance will have on the consolidated financial statements and footnote disclosures.

5

In January 2017, the FASB issued ASU 2017-04, Simplifying the Test for Goodwill Impairment, which eliminates the computation of the implied fair value of goodwill to measure a goodwill impairment charge. Instead, entities will record a goodwill impairment charge based on the excess of a reporting unit’s carrying amount over its fair value. The new standard is effective for interim and annual reporting periods beginning after December 15, 2019, with early adoption permitted. We expect the adoption of this standard will reduce the complexity surrounding the evaluation of goodwill for impairment. The impact of this new standard for the Company will depend on the outcomes of future goodwill impairment tests.

In May 2014, the FASB issued ASU No. 2014-09 (Topic 606), Revenue from Contracts with Customers, which provides a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and superseded most current revenue recognition guidance under Topic 605, Revenue Recognition. Under the new standard, an entity recognizes revenue when or as it satisfies a performance obligation by transferring control of a good or service to the customer, either at a point in time or over time. The new standard requires expanded disclosures, including how and when we satisfy performance obligations as well as additional disaggregated revenue information to be provided more frequently in the reporting process.

In March 2017, the FASB issued ASU No. 2017-07, “Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost.” This ASU requires the service cost component of net benefit costs to be disaggregated from all other components and be reported in the same line item or items as other compensation costs and allow only the service cost component to be eligible for capitalization when applicable. The other components of net benefit cost are required to be presented in the income statement separately from the service cost component and before income from operations. The Company adopted the requirements of this ASU as of January 1, 2018 on a retrospective basis. As such, the Company reclassified $2.9 million and $0.5 million from cost of sales and selling, general and administrative expenses, respectively to non-service retirement benefit income for the three months ended July 2, 2017 and reclassified $5.7 million and $1.0 million from cost of sales and selling, general and administrative expenses, respectively to non-service retirement benefit income for the six months ended July 2, 2017 to conform to current period presentation.

The Company adopted the requirements of Topic 606 as of January 1, 2018, using the modified retrospective transition method which required a cumulative-effect adjustment as of the date of adoption. Adoption of Topic 606 primarily impacted contracts for which revenue prior to fiscal year 2018 was recognized using the percentage of completion (“POC”), units-of-delivery or milestone methods, as these contracts are now recognized primarily using the POC cost-to-cost method to depict the transfer of control of the good or service to the customer as the work on the contract is performed. Also, to a much lesser extent, certain contracts for customized goods and services, certain products sold to the U.S. Government, and product repair contracts are now recognized over time, as control of the good or service produced transfers to the customer over time in accordance with the guidance in Topic 606. For impacted contracts that were in process at December 31, 2017, we calculated the difference in the life to date revenue (and related costs and expenses) between legacy accounting standards and Topic 606, with the cumulative effect of initially applying Topic 606 as an adjustment to the opening balance of retained earnings, as shown below. The prior year comparative information has not been restated and continues to be reported under the accounting standards in effect for those periods. While Topic 606 includes additional disclosures, as discussed within these Notes to the Condensed Consolidated Financial Statements, comparative disclosures with prior periods are not required in the year of adoption due to our use of the modified retrospective transition method.

The cumulative effect of the changes made to our consolidated January 1, 2018 balance sheet for the adoption ofTopic 606 were as follows (in millions):

	Balance at December 31, 2017		Topic ASC 606 Adjustments		Balance at January 1, 2018

Significant Accounting Policies Update

Our significant accounting policies are detailed in “Note 2: Summary of Significant Accounting Policies” of our Annual Report on Form 10-K for the year ended December 31, 2017. Significant changes to our accounting policies as a result of adopting Topic 606 are discussed below.

Revenue Recognition

We determine the appropriate method by which we recognize revenue by analyzing the nature of the products or services being provided as well as the terms and conditions of contracts or arrangements entered into with our customers. We account for a contract when it has approval and commitment from both parties, the rights of the parties are identified, payment terms are identified, the contract has commercial substance and collectability of consideration is probable. A contract’s transaction price is allocated to each distinct good or service (i.e., performance obligation) identified in the contract, and each performance obligation is valued based on its estimated relative standalone selling price. For standard products or services, list prices generally represent the standalone selling price. For performance obligations where list price is not available, we typically use the expected cost plus a margin approach to estimate the standalone selling price for that performance obligation. Approximately 60% of our revenue is recognized at a point in time, with the remaining 40% recognized over time.

Revenue recognized at a point in time relates primarily to the sale of standard or minimally customized products, with control transferring to the customer generally upon the transfer of title. This type of revenue arrangement is typical for our commercial contracts within the Instrumentation, Digital Imaging, and Aerospace and Defense Electronics segments, and to a lesser extent for certain commercial contracts within the Engineered Systems segment relating to the sale of standard hydrogen/oxygen gas generators. In limited circumstances, customer specified acceptance criteria exist. If we cannot objectively demonstrate that the product meets those specifications prior to the shipment, the revenue is deferred until customer acceptance is obtained. Performance obligations recognized at a point in time can include variable consideration, such as product returns and sales allowances. The estimation of this variable consideration and determination of whether to include estimated amounts as a reduction in the transaction price is based largely on an assessment of our anticipated performance and all information (historical, current and forecasted) that is reasonably available to us.

Revenue recognized over time relates primarily to contracts to design, develop and/or manufacture highly engineered products used in both defense and commercial applications. This type of revenue arrangement is typical of our U.S. government contracts and to a lesser extent for certain commercial contracts, with both contract types occurring across all segments. The customer typically controls the work in process as evidenced either by contractual termination clauses or by our right to payment for costs incurred to date plus a reasonable profit for products or services that do not have an alternative use. As

7

control transfers continuously over time on these contracts, revenue is recognized based on the extent of progress towards completion of the performance obligation. The selection of the method to measure progress towards completion requires judgment and is based on the nature of the products or services to be provided. We generally use the cost-to-cost measure of progress as this measure best depicts the transfer of control to the customer which occurs as we incur costs on our contracts. Under the cost-to-cost method, the extent of progress towards completion is measured based on the ratio of costs incurred to date to the total estimated costs at completion of the performance obligation. The transaction price in these arrangements may include estimated amounts of variable consideration, including award fees, incentive fees, or other provisions that can either increase or decrease the transaction price. We estimate variable consideration at the amount to which we expect to be entitled, and we include estimated amounts in the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur when the estimation uncertainty is resolved. The estimation of this variable consideration and determination of whether to include estimated amounts in the transaction price are based largely on an assessment of our anticipated performance and all information (historical, current and forecasted) that is reasonably available to us.

The majority of our over time contracts have a single performance obligation as the promise to transfer the individual goods or services is not separately identifiable from other promises in the contracts and, therefore, not distinct. Over time contracts are often modified to account for changes in contract specifications and requirements. We consider contract modifications to exist when the modification either creates new or changes the existing enforceable rights and obligations. Most of our contract modifications on over time contracts are for goods or services that are not distinct from the existing contract due to the significant integration service provided in the context of the contract and are accounted for as if they were part of that existing contract. The effect of a contract modification on the transaction price and our measure of progress for the performance obligation to which it relates, is recognized as an adjustment to revenue (either as an increase in or a reduction of revenue) on a cumulative catch-up basis.

For over time contracts using cost-to-cost, we have an Estimate at Completion (“EAC”) process in which management reviews the progress and execution of our performance obligations. This EAC process requires management judgment relative to assessing risks, estimating contract revenue and cost, and making assumptions for schedule and technical issues. This EAC process requires management’s judgment to make reasonably dependable cost estimates. Since certain contracts extend over a longer period of time, the impact of revisions in cost and revenue estimates during the progress of work may adjust the current period earnings through a cumulative catch-up basis. This method recognizes, in the current period, the cumulative effect of the changes on current and prior quarters. Additionally, if the current contract estimate indicates a loss, a provision is made for the total anticipated loss in the period that it becomes evident. Contract cost and revenue estimates for significant contracts are generally reviewed and reassessed quarterly. The majority of revenue recognized over time uses an EAC process. The net aggregate effects of these changes in estimates on contracts accounted for under the cost-to-cost method in the first six months of 2018 was less than $0.1 million of unfavorable revenue and operating income. None of the effects of changes in estimates on any individual contract were material to the condensed consolidated statements of income for any period presented.

While extended or non-customary warranties do not represent a significant portion of our revenue, we recognize warranty services as a separate performance obligations when it is material to the contract. When extended or non-customary warranties represents a separate performance obligation, the revenue is deferred and recognized ratably over the extended warranty period.

The timing of revenue recognition, billings and cash collections results in billed accounts receivable, unbilled receivables (contract assets), and customer advances and deposits (contract liabilities, which are included in accrued liabilities and other long-term liabilities) on the Condensed Consolidated Balance Sheet. Under the typical payment terms of our over time contracts, the customer pays us either performance-based payments or progress payments. Amounts billed and due from our customers are classified as receivables on the Condensed Consolidated Balance Sheet. We may receive interim payments as work progresses, although for some contracts, we may be entitled to receive an advance payment. We recognize a liability for these interim and advance payments in excess of revenue recognized and present it as a contract liability which is included within accrued liabilities and other long-term liabilities on the Condensed Consolidated Balance Sheet, which represented $101.6 million and $14.0 million as of July 1, 2018, and $110.3 million and $15.5 million as of January 1, 2018, respectively. Contract liabilities typically are not considered a significant financing component because these cash advances are used to meet working capital demands that can be higher in the early stages of a contract, and these cash advances protect us from the other party failing to adequately complete some or all of its obligations under the contract. When revenue recognized exceeds the amount billed to the customer, we record an unbilled receivable (contract asset) for the amount we are entitled to receive based on our enforceable right to payment. The unbilled receivable balance increased from the beginning of the year by $36.5 million, or 30.7%, primarily due to work performed ahead of billings on certain over time revenue contracts primarily in our Aerospace and Defense Electronics operating segment. Contract liabilities decreased from the beginning of the year by $10.3 million, or 8.1%, primarily due to the recognition of revenue in the year on customer advances that existed at the beginning of the year. The Company recognized revenue of $48.6 million during the quarter ended July 1, 2018 from contract liabilities that existed at the beginning of year. The Company recognizes the incremental costs of obtaining or fulfilling a contract as expense when incurred if the amortization period of the asset is one year or less. Incremental costs to obtain or fulfill contracts with an amortization period greater than one year were not material.

Remaining performance obligations represent the transaction price of firm orders for which work has not been performed as of the period end date and excludes unexercised contract options and potential orders under ordering-type contracts (e.g., indefinite-delivery, indefinite-quantity). As of July 1, 2018, the aggregate amount of the transaction price allocated to remaining performance obligations was $1,632.6 million. The Company expects approximately 83% of remaining performance obligations to be recognized into revenue within the next twelve months, with the remaining 17% recognized thereafter.

Note 2. Accumulated Other Comprehensive Loss

Note 3. Business Combinations, Goodwill and Acquired Intangible Assets

Acquisition of e2v

On March 28, 2017, Teledyne completed the acquisition of all of the outstanding common stock of e2v technologies plc (“e2v”) for $770.7 million, including stock options and assumed debt, net of $24.4 million of cash acquired. Principally located in Chelmsford, United Kingdom and Grenoble, France, most of e2v’s operations are included in the Digital Imaging and Aerospace and Defense Electronics segments. The Instrumentation segment includes a small portion of e2v’s operations.

The first six months of 2017 includes pretax charges of $25.2 million related to the acquisition of e2v, which included $12.8 million in transaction costs, including stamp duty, advisory, legal and other consulting fees and other costs recorded to selling, general and administrative expenses, $4.1 million in inventory fair value step-up amortization expense recorded to cost of sales, $2.3 million in bank bridge facility commitment expense recorded to interest expense and $6.0 million related to a foreign currency option contract expense to hedge the e2v purchase price recorded as other expense. Of these amounts, $6.5 million impacted segment operating income.

The unaudited proforma information below, as required by GAAP, assumes that e2v had been acquired at the beginning of the 2017 fiscal year and includes the effect of increased interest expense on net acquisition debt and the amortization of acquired intangible assets. The 2017 proforma amount also include $12.3 million in transaction costs, including legal and other consulting fees, $11.5 million in expense related to a foreign currency option contract to hedge the e2v purchase price, $2.8 million in bridge financing costs and $1.4 million in inventory fair value step-up amortization expense. These amounts totaling $28.0 million should be considered non-recurring costs that were necessary to complete the acquisition and are not indicative of the ongoing operations of the combined company.

This unaudited proforma financial information is presented for informational purposes only and is not necessarily indicative of the results of operations that actually would have resulted had the acquisition been in effect at the beginning of the periods presented. In addition, the unaudited proforma results are not intended to be a projection of future results and do not reflect any operating efficiencies or cost savings that might be achievable.

The following table presents proforma net sales, net income and earnings per share data assuming e2v was acquired at the beginning of the 2017 fiscal year:

	Second Quarter (a)		Six Months (a)
(unaudited - in millions, except per share amounts)	2017		2017
Net sales	$	671.1	$	1,330.2
Net income	$	60.1	$	73.2
Basic earnings per common share	$	1.71	$	2.08
Diluted earnings per common share	$	1.66	$	2.02

a) The above unaudited proforma information is presented for the e2v acquisition as it is considered a material acquisition.

SSI Acquisition

On July 20, 2017, a subsidiary of Teledyne acquired assets of Scientific Systems, Inc. (“SSI”) for $31.0 million in cash. Headquartered in State College, PA, SSI is part of the Instrumentation segment.

For a further description of the Company’s acquisition activity for fiscal year 2017, please refer to Note 3 of the Notes to Consolidated Financial Statements included in our 2017 Form 10-K.

Goodwill and Acquired Intangible Assets

Teledyne’s goodwill was $1,758.9 million at July 1, 2018 and $1,776.7 million at December 31, 2017. The decrease in the balance of goodwill in 2018 included the impact of exchange rate changes, partially offset by adjustments for the purchase accounting allocation for the e2v and SSI acquisitions. Teledyne’s net acquired intangible assets were $368.6 million at July 1, 2018 and $398.9 million at December 31, 2017. The decrease in the balance of net acquired intangible assets reflected amortization and the impact of exchange rate changes, partially offset by adjustments for the purchase accounting allocation for the SSI acquisition. The Company completed the process of specifically identifying the amount to be assigned to certain assets, including acquired intangible assets, and liabilities and the related impact on taxes and goodwill for the e2v and SSI acquisitions, including the allocation by segment, resulting in an increase to goodwill of $3.9 million for e2v and $4.8 million for SSI in 2018.

Note 4. Derivative Instruments

Teledyne transacts business in various foreign currencies and has international sales and expenses denominated in foreign currencies, subjecting the Company to foreign currency risk. The Company’s primary foreign currency risk management objective is to protect the US dollar value of future cash flows and minimize the volatility of reported earnings. All derivatives are recorded on the balance sheet at fair value. As discussed below, the accounting for gains and losses resulting from changes in fair value depends on the use of the derivative and whether it is designated and qualifies for hedge accounting. The Company utilizes foreign currency forward contracts to reduce the volatility of cash flows primarily related to forecasted revenues and expenses denominated in Canadian dollars for our Canadian companies, including DALSA and in British pounds for our UK companies, including e2v. These contracts are designated and qualify as cash flow hedges. The Company has converted a US dollar denominated, variable rate debt obligation into a euro fixed rate obligation using a receive-float, pay fixed cross currency swap. This cross currency swap is designated as a cash flow hedge.

Cash Flow Hedging Activities

The effectiveness of the forward contract cash flow hedge, which exclude time value, and the cross currency swap cash flow hedge is assessed prospectively and retrospectively on a monthly basis using regression analysis, as well as using other timing and probability criteria. To receive hedge accounting treatment, all hedging relationships are formally documented at the inception of the hedges and must be highly effective in offsetting changes to future cash flows on hedged transactions. The effective portion of the cash flow hedge forward contracts’ gains or losses resulting from changes in the fair value of these hedges is initially reported, net of tax, as a component of AOCI in stockholders’ equity until the underlying hedged item is reflected in our consolidated statements of income, at which time the effective amount in AOCI is reclassified to cost of sales in our consolidated statements of income. For the cross currency swap cash flow hedge, effective amounts are recorded in AOCI, and reclassified into interest expense in the consolidated statements of income. In addition, for the cross currency swap an amount is reclassified from AOCI to other income and expense each reporting period, to offset the earnings impact of the remeasurement of the hedged liability. Net deferred losses recorded in AOCI, net of tax, for the forward contracts that will mature in the next twelve months total $0.3 million. These losses are expected to be offset by anticipated gains in the value of the forecasted underlying hedged item. Amounts related to the cross currency swap expected to be reclassified from AOCI into income in the coming twelve months total $2.8 million.

In the event that the gains or losses in AOCI are deemed to be ineffective, the ineffective portion of gains or losses resulting from changes in fair value, if any, is reclassified to other income and expense. In the event that the underlying forecasted transactions do not occur, or it becomes remote that they will occur, within the defined hedge period, the gains or losses on the related cash flow hedges will be reclassified from AOCI to other income and expense. During the current reporting period, all forecasted transactions occurred and, therefore, there were no such gains or losses reclassified to other income and expense. As of July 1, 2018, Teledyne had foreign currency forward contracts designated as cash flow hedges to buy Canadian dollars and to sell U.S. dollars totaling $102.4 million. These foreign currency forward contracts have maturities ranging from September 2018 to February 2020. Together the contracts had a negative fair value of $2.1 million. The cross currency swap has notional amounts of €93.0 million equivalent to $100.0 million, and matures in October 2019.

The effect of derivative instruments designated as cash flow hedges in the condensed consolidated financial statements for the second quarter ended July 1, 2018 and July 2, 2017 was as follows (in millions):

	Second Quarter						Six Months
	2018			2017			2018			2017
Net gain (loss) recognized in AOCI (a)	$	3.6		$	(3.4	)	$	(0.1	)	$	(2.9	)
Net gain (loss) reclassified from AOCI into cost of sales (a)	$	0.8		$	(0.6	)	$	2.0		$	(0.7	)

a)    Effective portion, pre-tax

b)     Amount reclassified to offset earnings impact of liability hedged by cross currency swap

c)     Amount excluded from effectiveness testing

Non-Designated Hedging Activities

In addition, the Company utilizes foreign currency forward contracts to mitigate foreign exchange rate risk associated with foreign-currency-denominated monetary assets and liabilities, including intercompany receivables and payables. As of July 1, 2018, Teledyne had non-designated foreign currency contracts of this type in the following pairs (in millions):

Contracts to Buy			Contracts to Sell
Currency	Amount		Currency	Amount
Canadian Dollars	C$	211.2	U.S. Dollars	US$	162.8
Canadian Dollars	C$	15.1	Euros	€	9.9
Euros	€	55.0	Great Britain Pounds	£	48.5
Great Britain Pounds	£	1.3	Australian Dollars	A$	2.3
Great Britain Pounds	£	91.1	U.S. Dollars	US$	121.4
Singapore Dollars	S$	2.1	U.S. Dollars	US$	1.6
Euros	€	39.4	U.S. Dollars	US$	46.5
U.S. Dollars	US$	0.9	Japanese Yen	¥	100.0
Danish Krone	DKR	45.5	U.S. Dollars	US$	7.2

The above table includes non-designated hedges derived from terms contained in triggered or previously designated cash flow hedges. The gains and losses on these derivatives which are not designated as hedging instruments are intended to, at a minimum, partially offset the transaction gains and losses recognized in earnings. Teledyne does not use foreign currency forward contracts for speculative or trading purposes.

The effect of derivative instruments not designated as cash flow hedges recognized in other income and expense for the second quarter and six months ended July 1, 2018 was expense of $17.0 million and $17.8 million, respectively. The effect of derivative instruments not designated as cash flow hedges in other income and expense for the second quarter and six months ended July 2, 2017 was expense of $0.5 million and $6.5 million, respectively. These losses were largely offset by gains in the value of the underlying hedged item.

Fair Value of Derivative Financial Instruments

The Company has elected to use the income approach to value the derivatives, using observable Level 2 market expectations at measurement date and standard valuation techniques to convert future amounts to a single present amount. Level 2 inputs for the valuations are limited to quoted prices for similar assets or liabilities in active markets (specifically futures contracts on LIBOR and EURIBOR) and inputs other than quoted prices that are observable for the asset or liability (specifically LIBOR and EURIBOR cash and swap rates, foreign currency forward rates and cross currency basis spreads). Mid-market pricing is used as a practical expedient for fair value measurements. The fair value measurement of an asset or liability must reflect the nonperformance risk of the entity and the counterparty. Therefore, the impact of the counterparty’s creditworthiness when in an asset position and the Company’s creditworthiness when in a liability position has also been factored into the fair value measurement of the derivative instruments and did not have a material impact on the fair value of these derivative instruments. Both the counterparty and the Company are expected to continue to perform under the contractual terms of the instruments.

The fair values of the Company’s derivative financial instruments are presented below. All fair values for these derivatives were measured using Level 2 information as defined by the accounting standard hierarchy (in millions):

Asset/(Liability) Derivatives	Balance sheet location	July 1, 2018			December 31, 2017
Derivatives designated as hedging instruments:
Cash flow forward contracts	Other assets	$	0.3		$	3.8
Cash flow cross currency swap	Other assets	—			2.2

Total derivatives designated as hedging instruments		(10.5		)	(7.9		)
Derivatives not designated as hedging instruments:
Non-designated forward contracts	Other current assets	0.5			4.9
Non-designated forward contracts	Accrued liabilities	(6.8		)	(1.2		)
Total derivatives not designated as hedging instruments		(6.3		)	3.7
Total (liability) asset derivatives		$	(16.8	)	$	(4.2	)

Note 5. Earnings Per Share

For the second quarter of 2018 no stock options were excluded in the computation of diluted earnings per share. For the first six months of 2018, 185,292 stock options were excluded in the computation of diluted earnings per share because they had exercise prices that were greater than the weighted average market price of the Company’s common stock during the period. For the second quarter and first six months of 2017, 900 stock options were excluded in the computation of diluted earnings per share because they had exercise prices that were greater than the weighted average market price of the Company’s common stock during the period.

The weighted average number of common shares used in the calculation of basic and diluted earnings per share consisted of the following (in millions):

	Second Quarter		Six Months
	2018	2017	2018	2017
Weighted average basic common shares outstanding	35.8	35.2	35.7	35.2
Effect of dilutive securities (primarily stock options)	1.2	1.0	1.2	1.0
Weighted average diluted common shares outstanding	37.0	36.2	36.9	36.2

Note 6. Stock-Based Compensation Plans

Teledyne has long-term incentive plans pursuant to which it has granted non-qualified stock options, restricted stock and performance shares to certain employees. The Company also has non-employee Board of Director stock compensation plans, pursuant to which non-qualified stock options and common stock, and beginning in 2015 restricted stock units, have been issued to its directors. After 2014, non-employee directors no longer receive non-qualified stock options.

Stock Incentive Plan

The following disclosures are based on stock options granted to Teledyne’s employees and directors. Stock option compensation expense was $5.4 million for the second quarter of 2018 and was $3.7 million for the second quarter of 2017. Stock option compensation expense was $10.3 million for the first six months of 2018 and was $7.8 million for the first six months of 2017. Employee stock option grants are charged to expense evenly over the three year vesting period. For 2018, the Company currently expects approximately $21.1 million in stock option compensation expense based on stock options currently outstanding. This amount can be impacted by employee retirements and terminations or stock options granted during the remainder of the year. The Company issues shares of common stock upon the exercise of stock options.

The following assumptions were used in the valuation of stock options granted in 2018:

	2018
Expected volatility	31.0%
Risk-free interest rate range	1.99% to 2.58%
Expected life in years	6.8
Expected dividend yield	—

Based on the assumptions used in the valuation of stock options, the grant date weighted average fair value of stock options granted in 2018 was $71.79 per share.

Stock option transactions for the second quarter and six months ended July 1, 2018 are summarized as follows:

	2018
	Second Quarter				Six Months
	Shares		Weighted Average Exercise Price		Shares		Weighted Average Exercise Price
Beginning balance	2,463,010		$	100.94	2,285,703		$	83.73

Performance Share Plan and Restricted Stock Award Program

In the first quarter of 2018, the Company issued 6,481 shares of Teledyne common stock for the first of three annual payouts under the 2015 to 2017 Performance Share Plan. A total of 31,117 shares remain to be issued in equal installments in 2019 and 2020. In the first quarter of 2018, the performance cycle for the three-year period ending December 31, 2020, was set.  Under the plan, the target number of shares that could be issued in three equal installments in 2021, 2022 and 2023, is 26,814 (with a maximum of 53,607).

The following table shows the restricted stock activity for the first six months of 2018:

	Shares		Weighted average fair value per share
Balance, December 31, 2017	88,436		$	90.63
Granted	16,733		$	171.80

Forfeited/Canceled	(1,571	)	$	89.93
Balance, July 1, 2018	74,743		$	108.01

Note 7. Inventories

Inventories are stated at current cost net of reserves for excess, slow moving and obsolete inventory, less progress payments. Inventories are valued under the FIFO method, LIFO method and average cost method. Inventories at cost determined on the average cost or the FIFO methods were $342.4 million at July 1, 2018 and $348.6 million at December 31, 2017. The remainder of the inventories using the LIFO method were $46.9 million at July 1, 2018 and $63.6 million at December 31, 2017. Interim LIFO calculations are based on the Company’s estimates of expected year-end inventory levels and costs since an actual valuation of inventory under the LIFO method can be made only at the end of each year based on the inventory levels and costs at that time. Because these estimates are subject to many factors beyond the Company’s control, interim results are subject to the final year-end LIFO inventory valuation.

Note 8. Warranty Reserve

Some of the Company’s products are subject to specified warranties, and the Company provides for the estimated cost of product warranties. The adequacy of the warranty reserve is assessed regularly, and the reserve is adjusted as necessary based on a review of historic warranty experience with respect to the applicable business or products, as well as the length and actual terms of the warranties. The warranty reserve is included in current and long-term accrued liabilities on the balance sheet.

Note 9. Income Taxes

The income tax provision is calculated using an estimated annual effective tax rate, based upon expected annual income, permanent items, statutory rates and planned tax strategies in the various jurisdictions in which the Company operates. However, losses in certain jurisdictions and discrete items, such as the resolution of uncertain tax positions, are treated separately.

On December 22, 2017, the Tax Cuts and Jobs Act of 2017 (“Tax Act”) was enacted. The Tax Act significantly revised the U.S. corporate income tax by, among other things, lowering corporate income tax rates, implementing the territorial tax system and imposing a repatriation tax on deemed repatriated earnings of foreign subsidiaries. As a result of the Tax Act, Teledyne incurred provisional charges of $4.7 million in the fourth quarter of 2017 primarily due to the repatriation tax and the remeasurement of U.S. deferred tax assets and liabilities. The impacts of the Tax Act may differ from this estimate, possibly materially (and the amount of the provisional charge may accordingly be adjusted over the course of 2018), due to changes in interpretations and assumptions Teledyne has made, guidance that may be issued, and actions Teledyne may take as a result of the Tax Act. In the first quarter of 2018, the provisional charge was adjusted by an additional $0.6 million.

The Company’s effective income tax rate for the second quarter and first six months of 2018 was 17.7% and 18.3%, respectively. The Company’s effective income tax rate for the second quarter and first six months of 2017 was 21.3% and 22.6%, respectively. The second quarter and first six months of 2018 includes net discrete income tax benefits of $3.4 million and $5.5 million, respectively. The 2018 second quarter and first six months net discrete tax benefits includes $4.7 million and $7.7 million, respectively, related to share-based accounting. The first six months of 2018 includes the first quarter $0.6 million increase in the provisional charge. The second quarter and first six months of 2017 included net discrete income tax benefits of $4.6 million and $6.0 million, respectively. The 2017 second quarter and first six months net discrete tax benefits includes an $8.1 million income tax benefit related to the release of valuation allowance for which the deferred tax assets are now determined more-likely-than-not to be realizable and $4.6 million in income tax expense related to adjustments for uncertain tax positions. The 2017 second quarter and first six months net discrete tax benefits includes $1.2 million and $2.8 million, respectively, related to share-based accounting. Excluding the net discrete income tax benefits in both periods and the increase in the provisional charge, the effective tax rates would have been 21.0% for the second quarter of 2018 and 21.3% for the first six months of 2018. Excluding net discrete income tax benefits in both 2017 periods, the effective tax rates would have been 27.4% for the second quarter and 27.7% for the first six months of 2017. The decrease in the effective tax rate in both 2018 periods, primarily reflects the lower corporate income tax rates as part of the Tax Act.

Teledyne estimates the fair value of its long-term debt based on debt of similar type, rating and maturity and at comparable interest rates. The Company’s long-term debt is considered a level 2 fair value hierarchy and is valued based on observable market data. The estimated fair value of Teledyne’s long-term debt at July 1, 2018 and December 31, 2017, approximated the carrying value.

At July 1, 2018, the Company had $6.0 million in capital leases, of which $1.3 million is current. At December 31, 2017, the Company had $6.7 million in capital leases, of which $1.3 million was current. At July 1, 2018, Teledyne had $27.7 million in outstanding letters of credit.

Note 11. Lawsuits, Claims, Commitments, Contingencies and Related Matters

For a further description of the Company’s commitments and contingencies, reference is made to Note 14 of the Company’s financial statements as of and for the fiscal year ended December 31, 2017, included in the 2017 Form 10-K.

At July 1, 2018, the Company’s reserves for environmental remediation obligations totaled $4.7 million, of which $0.6 million is included in current accrued liabilities. At December 31, 2017, the Company’s reserves for environmental remediation obligations totaled $5.1 million. The Company periodically evaluates whether it may be able to recover a portion of future costs for environmental liabilities from its insurance carriers and from third parties. The timing of expenditures depends on a number of factors that vary by site, including the nature and extent of contamination, the number of potentially responsible parties, the timing of regulatory approvals, the complexity of the investigation and remediation, and the standards for remediation. The Company expects that it will expend present accruals over many years and will complete remediation of all sites with which it has been identified in up to 30 years.

A number of other lawsuits, claims and proceedings have been or may be asserted against the Company, including those pertaining to product liability, acquisitions, patent infringement, contracts, environmental, employment and employee benefits matters. While the outcome of litigation cannot be predicted with certainty, and some of these lawsuits, claims or proceedings may be determined adversely to the Company, management does not believe that the disposition of any such pending matters is likely to have a material adverse effect on the Company’s financial statements.

Note 12. Pension Plans and Postretirement Benefits

For the domestic pension plan, the discount rate decreased to 4.02% in 2018 compared with a 4.54% discount rate used in 2017. Pension expense allocated to contracts pursuant to U.S. Government Cost Accounting Standards (“CAS”) was $3.3 million and $3.5 million for the second quarter of 2018 and 2017, respectively. Pension expense allocated to contracts pursuant to U.S. Government Cost Accounting Standards (“CAS”) was $6.5 million and $6.9 million for the first six months of 2018 and 2017, respectively. Pension expense determined under CAS can generally be recovered through the pricing of products and services sold to the U.S. Government. Teledyne did not make any cash pension contributions to its domestic qualified pension plan since 2013. No cash pension contributions are planned for 2018 for the domestic qualified pension plan.

Item 2.    Management’s Discussion and Analysis of Financial Condition and Results of Operations

Teledyne Technologies Incorporated provides enabling technologies for industrial growth markets that require advanced technology and high reliability. These markets include aerospace and defense, factory automation, air and water quality environmental monitoring, electronics design and development, oceanographic research, deepwater oil and gas exploration and production, medical imaging and pharmaceutical research. Our products include digital imaging sensors, cameras and systems within the visible, infrared and X-ray spectra, monitoring and control instrumentation for marine and environmental applications, harsh environment interconnects, electronic test and measurement equipment, aircraft information management systems, and defense electronics and satellite communication subsystems. We also supply engineered systems for defense, space, environmental and energy applications. We differentiate ourselves from many of our direct competitors by having a customer and company-sponsored applied research center that augments our product development expertise.

Effective January 1, 2018, Teledyne adopted Accounting Standards Update No. 2014-09 (Topic 606), “Revenue from Contracts with Customers”, using the modified retrospective transition method. Prior period comparative information is not adjusted and is reported under the accounting standards in effect for that period. The cumulative effect of adopting the new standard resulted in an immaterial increase to retained earnings as of January 1, 2018. See Note 1 to these condensed consolidated financial statements for additional information.

In the second quarter of 2018, we realigned the reporting structure for certain of our microwave product groupings. These products, acquired with the acquisition of e2v were formerly reported as part of the Aerospace and Defense Electronics segment and are now reported as part of the Digital Imaging segment. Previously reported segment data has been adjusted to reflect this change. Total sales for these products were $24.2 million for fiscal year 2017.

Strategy/Overview

Our strategy continues to emphasize growth in our core markets of instrumentation, digital imaging, aerospace and defense electronics and engineered systems. Our core markets are characterized by high barriers to entry and include specialized products and services not likely to be commoditized. We intend to strengthen and expand our core businesses with targeted acquisitions and through product development. We continue to focus on balanced and disciplined capital deployment among capital expenditures, acquisitions and share repurchases. We aggressively pursue operational excellence to continually improve our margins and earnings. At Teledyne, operational excellence includes the rapid integration of the businesses we acquire. Using complementary technology across our businesses and internal research and development, we seek to create new products to grow our company and expand our addressable markets. We continue to evaluate our businesses to ensure that they are aligned with our strategy.

On March 28, 2017, we purchased all of the common stock of e2v technologies plc (“e2v”) for $770.7 million, including stock options and assumed debt, net of $24.4 million of cash acquired. Most of e2v’s operations are included in the Digital Imaging and Aerospace and Defense Electronics segments. The Instrumentation segment includes a small portion of e2v’s operations. See the Recent Acquisitions section for more information on the acquisition.

e2v, with principal locations in Chelmsford, United Kingdom and Grenoble, France, which was acquired on March 28, 2017, had sales of approximately £236 million for its fiscal year ended March 31, 2016. Teledyne funded the acquisition of e2v with borrowings under its credit facility and cash on hand as well as $100.0 million in term loans.

e2v provides high performance image sensors and custom camera solutions and application specific standard products for the machine vision market. In addition, e2v provides high performance space qualified imaging sensors and arrays for space science and astronomy. e2v also produces components and subsystems that deliver high reliability radio frequency power generation for healthcare, industrial and defense applications. Finally, e2v provides high reliability semiconductors and board-level solutions for use in aerospace, space and communications applications.

SSI Acquisition

On July 20, 2017, Teledyne Instruments, Inc. completed the acquisition of assets of Scientific Systems, Inc. (“SSI”) for $31.0 million in cash. A subsequent cash payment of $0.3 million related to a purchase price adjustment was made in the fourth quarter of 2017. Headquartered in State College, Pa., SSI manufactures precision components and specialized subassemblies used primarily in analytical and diagnostic instrumentation, such as high performance liquid chromatography systems and specific medical devices. SSI designs and manufactures high pressure positive-displacement piston pumps for a wide variety of analytical, clinical, sample prep and fluid-metering applications and is part of the Instrumentation segment.

Income Taxes

The income tax provision is calculated using an estimated annual effective tax rate, based upon estimates of annual income, permanent items, statutory tax rates and planned tax strategies in the various jurisdictions in which we operate except that certain loss jurisdictions and discrete items, such as the resolution of uncertain tax positions and share-based accounting income tax benefits, are treated separately.

On December 22, 2017, the Tax Cuts and Jobs Act of 2017 (“Tax Act”) was enacted. The Tax Act significantly revised the U.S. corporate income tax by, among other things, lowering corporate income tax rates, implementing the territorial tax system and imposing a repatriation tax on deemed repatriated earnings of foreign subsidiaries. As a result of the Tax Act, Teledyne incurred provisional charges of $4.7 million in the fourth quarter of 2017 primarily due to the repatriation tax and the remeasurement of U.S. deferred tax assets and liabilities. The impacts of the Tax Act may differ from this estimate, possibly materially (and the amount of the provisional charge may accordingly be adjusted over the course of 2018), due to changes in interpretations and assumptions Teledyne has made, guidance that may be issued, and actions Teledyne may take as a result of the Tax Act. In the first quarter of 2018, the provisional charge was adjusted by an additional $0.6 million.

The Company’s effective income tax rate for the second quarter of 2018 was 17.7%, compared with 21.3% for the second quarter of 2017. The second quarter of 2018 reflected net discrete income tax benefits of $3.4 million. This amount includes a $4.7 million income tax benefit related to share-based accounting. The 2017 second quarter net discrete tax benefits includes an $8.1 million income tax benefit related to the release of valuation allowance for which the deferred tax assets are now determined more-likely-than-not to be realizable and $4.6 million in income tax expense related to adjustments for uncertain tax positions. The 2017 second quarter also included net discrete tax benefits includes $1.2 million related to share-based accounting. Excluding the net discrete income tax benefits, the effective tax rates would have been 21.0% for the second quarter of 2018 and 27.4% for the second quarter of 2017. The decrease in the effective tax rate in both 2018 periods, primarily reflects the lower corporate income tax rates as part of the Tax Act. The Company’s annual effective tax rate for fiscal year 2018 is expected to be 21.3%, based on the projected mix of earnings before tax by jurisdiction, excluding the impact of any matters that would be treated as discrete.

Our goodwill was $1,758.9 million at July 1, 2018 and $1,776.7 million at December 31, 2017. The decrease in the balance of goodwill in 2018 included the impact of exchange rate changes, partially offset by adjustments for the purchase accounting allocation for the e2v and SSI acquisitions. Teledyne’s net acquired intangible assets were $368.6 million at July 1, 2018 and $398.9 million at December 31, 2017. The decrease in the balance of net acquired intangible assets reflected amortization and

the impact of exchange rate changes, partially offset by adjustments for the purchase accounting allocation for the SSI acquisition. The Company completed the process of specifically identifying the amount to be assigned to certain assets, including acquired intangible assets, and liabilities and the related impact on taxes and goodwill for the e2v and SSI acquisitions, resulting in an increase to goodwill of $3.9 million for e2v and $4.8 million for SSI in 2018.

Financing activities used cash of $90.9 million for the first six months of 2018, compared with cash provided by financing activities of $599.6 million for the first six months of 2017. Financing activities for the first six months of 2018 reflected net payments against the $750.0 million credit facility of $115.0 million. Financing activities for the first six months of 2017 reflected net borrowings from the $750.0 million credit facility of $255.0 million and the proceeds from a $100.0 million term loan, primarily to fund the e2v acquisition. Proceeds from the exercise of stock options were $23.8 million and $11.7 million for the first six months of 2018 and 2017, respectively. In March 2017, Teledyne entered into a $100.0 million term loan with a maturity date of October 30, 2019. Subsequently, in March 2017, Teledyne entered into a cross currency swap to effectively convert the $100.0 million term loan to a 93.0 million Euro denominated instrument with a fixed euro interest rate of 0.7055%. The proceeds from the term loan were used in connection with the acquisition of e2v. Teledyne used the proceeds of the private placement to, among other things, repay indebtedness incurred in connection with the acquisition of e2v and for general corporate purposes.

Our principal cash and capital requirements are to fund working capital needs, capital expenditures, income tax payments, pension contributions, debt service requirements and the stock repurchase program, as well as acquisitions. It is anticipated that operating cash flow, together with available borrowings under the credit facility described below, will be sufficient to meet these requirements over the next twelve months. We may raise other forms of debt capital, depending on financial, market and economic conditions. We may need to raise additional capital to support acquisitions. We currently expect to spend approximately $90.0 million for capital expenditures in 2018, of which $47.2 million has been spent in the first six months of 2018. No cash pension contributions have been made since 2013 or are planned for the remainder of 2018 for the domestic qualified pension plan.

Total debt, including capital lease obligations, at July 1, 2018 was $952.0 million. At July 1, 2018, $50.0 million was outstanding under the $750.0 million credit facility. At July 1, 2018, Teledyne had $27.7 million in outstanding letters of credit. Available borrowing capacity under the $750.0 million credit facility, which is reduced by borrowings and certain outstanding letters of credit, was $674.9 million at July 1, 2018. The credit agreements require the Company to comply with various financial and operating covenants and at July 1, 2018, the Company was in compliance with these covenants.

As of July 1, 2018, the Company had an adequate amount of margin between required financial covenant ratios (as required by applicable credit agreements) and our actual ratios. At July 1, 2018, the required financial ratios and the actual ratios were as follows:

$750.0 million Credit Facility expires December 2020 and $175.5 million term loans due through January 2022 (issued in October 2012) and $100.0 million term loan due October 2019 (issued in March 2017)
Financial Covenants	Requirement	Actual Measure
Consolidated Leverage Ratio (Net Debt/EBITDA) (a)	No more than 3.25 to 1	2.0 to 1
Consolidated Interest Coverage Ratio (EBITDA/Interest) (b)	No less than 3.0 to 1	17.0 to 1
$614.2 million Private Placement Senior Notes due from 2019 to 2024
Financial Covenants	Requirement	Actual Measure
Consolidated Leverage Ratio (Net Debt/EBITDA) (a)	No more than 3.25 to 1	2.0 to 1
Consolidated Interest Coverage Ratio (EBITDA/Interest) (b)	No less than 3.0 to 1	17.0 to 1

a) The Consolidated Leverage Ratio is equal to Net Debt/EBITDA as defined in our private placement note purchase agreement and our $750.0 million credit agreement.

b) The Consolidated Interest Coverage Ratio is equal to EBITDA/Interest as defined in our private placement note purchase agreement and our $750.0 million credit agreement.

Our liquidity is not dependent upon the use of off-balance sheet financial arrangements. We have no off-balance sheet financing arrangements that incorporate the use of special purpose entities or unconsolidated entities.

Critical Accounting Policies

Our critical accounting policies are those that are reflective of significant judgments and uncertainties, and may potentially result in materially different results under different assumptions and conditions. Our critical accounting policies are the following: revenue recognition; accounting for pension plans; accounting for business combinations, goodwill, acquired intangible assets and other long-lived assets; and accounting for income taxes.

For additional discussion of the application of the critical accounting policies and other accounting policies, see Note 1 to these condensed consolidated financial statements and also Management’s Discussion and Analysis of Financial Condition and Results of Operations — Critical Accounting Policies and Note 2 of the Notes to Consolidated Financial Statements included in Teledyne’s 2017 Form 10-K.

Safe Harbor Cautionary Statement Regarding Forward-Looking Information

From time to time we make, and this report contains, forward looking statements, as defined in the Private Securities Litigation Reform Act of 1995, directly or indirectly relating to sales, earnings, operating margin, growth opportunities, acquisitions and divestitures, product sales, capital expenditures, pension matters, stock option compensation expense, the credit facility, interest expense, severance and relocation and facility consolidation costs, environmental remediation costs, stock repurchases, taxes, exchange rate fluctuations and strategic plans. Forward-looking statements are generally accompanied by words such as “estimate”, “project”, “predict”, “believes” or “expect”, that convey the uncertainty of future events or outcomes. All statements made in this Management’s Discussion and Analysis of Financial Condition and Results of Operations and in other sections of this Form 10-Q that are not historical in nature should be considered forward-looking.

Actual results could differ materially from these forward-looking statements. Many factors could change the anticipated results, including: disruptions in the global economy; changes in demand for products sold to the defense electronics, instrumentation, digital imaging, energy exploration and production, commercial aviation, semiconductor and communications markets; funding, continuation and award of government programs; cuts to defense spending resulting from existing and future deficit reduction measures; impacts from the United Kingdom’s decision to exit the European Union; uncertainties related to the policies of the U.S. Presidential Administration; the imposition and expansion of, and responses to, trade sanctions and tariffs; and threats to the security of our confidential and proprietary information, including cyber security threats. Lower oil and natural gas prices, as well as instability in the Middle East or other oil producing regions, and new regulations or restrictions relating to energy production, including with respect to hydraulic fracturing, could negatively affect the Company’s businesses that supply the oil and gas industry. Increasing fuel costs could negatively affect the markets of our commercial aviation businesses. In addition, financial market fluctuations affect the value of the Company’s pension assets.

Information regarding the impact of the Tax Act consists of preliminary estimates which are forward-looking statements and are subject to change, possibly materially, as the company completes its financial statements. Information regarding the impact of the Tax Act is based on our current calculations, as well as our current interpretations, assumptions and expectations relating to the Tax Act, which are subject to change.

Changes in the policies of U.S. and foreign governments, could result, over time, in reductions and realignment in defense or other government spending and further changes in programs in which the company participates.

While the Company’s growth strategy includes possible acquisitions, we cannot provide any assurance as to when, if or on what terms any acquisitions will be made. Acquisitions involve various inherent risks, such as, among others, our ability to integrate acquired businesses, retain customers and achieve identified financial and operating synergies. There are additional risks associated with acquiring, owning and operating businesses outside of the United States, including those arising from U.S. and foreign government policy changes or actions and exchange rate fluctuations.

While we believe our internal and disclosure control systems are effective, there are inherent limitations in all control systems, and misstatements due to error or fraud may occur and not be detected.

Readers are urged to read our periodic reports filed with the Securities and Exchange Commission for a more complete description of our Company, its businesses, its strategies and the various risks that we face. Various risks are identified in Teledyne’s 2017 Form 10-K and subsequent Quarterly Reports on Form 10-Q.

We assume no duty to publicly update or revise any forward-looking statements, whether as a result of new information or otherwise.

Item 3.     Quantitative and Qualitative Disclosures About Market Risk

Except as set forth below, there were no material changes to the information provided under “Item 7A, Quantitative and Qualitative Disclosure About Market Risk” included in our 2017 Form 10-K.

Market Risk

We are exposed to various market risks, including changes in foreign currency exchange rates and interest rates. Foreign currency forward contracts are used primarily to hedge anticipated exposures. We do not enter into derivatives or other financial instruments for trading or speculative purposes.

Foreign Currency Exchange Rate Risk

Notwithstanding our efforts to mitigate portions of our foreign currency exchange rate risks, there can be no assurance that our hedging activities will adequately protect us against the risks associated with foreign currency fluctuations. A hypothetical 10 percent price change in the U.S. dollar from its value at July 1, 2018 would result in a decrease or increase in the fair value of our foreign currency forward contracts designated as cash flow hedges to buy Canadian dollars and to sell U.S. dollars by approximately $10.2 million. A hypothetical 10 percent price change in the U.S. dollar from its value at July 1, 2018 would result in a decrease or increase in the fair value of our Euro/U.S. Dollar cross currency swap designated as a cash flow hedge by approximately $10.1 million. For additional information please see Derivative Instruments discussed in Note 4 to these condensed consolidated financial statements.

Interest Rate Exposure

We are exposed to market risk through the interest rate on our borrowings under our $750.0 million credit facility and our $275.5 million in term loans. Borrowings under our credit facility and our term loans are at variable rates which are, at our option, tied to a Eurocurrency rate equal to LIBOR (London Interbank Offered Rate) plus an applicable rate or a base rate as defined in our credit agreements. Eurocurrency rate loans may be denominated in U.S. dollars or an alternative currency as defined in the credit agreements. Eurocurrency or LIBOR based loans under the credit facility typically have terms of one, two, three or nine months and the interest rate for each such loan is subject to change if the loan is continued or converted following the applicable maturity date. The Company has not drawn any loans with a term longer than three months under the credit facility. Base rate loans have interest rates that primarily fluctuate with changes in the prime rate. Interest rates are also subject to change based on our consolidated leverage ratio as defined in the credit agreements. As of July 1, 2018, we had $325.5 million in outstanding indebtedness under our credit facility and term loans. A 100 basis point increase in interest rates would result in an increase in annual interest expense of approximately $3.3 million, assuming the $325.5 million in debt was outstanding for the full year.

Item 4. Controls and Procedures

Our disclosure controls and procedures are designed to ensure that information required to be disclosed in reports that we file or submit under the Securities Exchange Act of 1934, are recorded, processed, summarized and reported within the time periods specified in the rules and forms of the Securities and Exchange Commission and to provide reasonable assurance that information required to be disclosed by us in such reports is accumulated and communicated to the Company’s management, including its principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding required disclosure. Our Chairman and Chief Executive Officer and our Senior Vice President and Chief Financial Officer, with the participation and assistance of other members of management, have reviewed the effectiveness of our disclosure controls and procedures and have concluded that the disclosure controls and procedures, as of July 1, 2018, are effective at the reasonable assurance level.

In connection with our evaluation during the quarterly period ended July 1, 2018, we have made no changes in our internal controls over financial reporting that have materially affected or are reasonably likely to materially affect our internal controls over financial reporting.

31

PART II OTHER INFORMATION

Item 1. Legal Proceedings

See Item 1 of Part 1, “Financial Statements -- Note 11 -- Lawsuits, Claims, Commitments, Contingencies and Related Matters.”

 Item 1A. Risk Factors

Other than as set forth below, there are no material changes to the risk factors previously disclosed in our 2017 Form 10-K in response to Item 1A to Part 1 of Form 10-K. See also Part I Item 3, Quantitative and Qualitative Disclosures About Market Risk, for updated disclosures about interest rate exposure and exchange rate risks.

Escalating trade tensions and the adoption or expansion of tariffs and trade restrictions could negatively impact us.

The U.S. Presidential Administration has recently announced tariffs on steel and aluminum products and materials imported into the United States. The Administration has also implemented or announced plans to impose tariffs on a wide-range of goods imported from China. Various countries and economic regions have announced plans or intentions to impose retaliatory tariffs on a wide-range of products they import from the U.S. These newly imposed or threatened U.S. tariffs and retaliatory tariffs could have the effect of increasing the cost of materials for our products, which could result in our products becoming less competitive or generating lower margins. The tariffs could also result in disruptions to our supply chain, as suppliers struggle to fill orders from companies trying to purchase goods in bulk ahead of announced tariffs. We may also need to find new suppliers and components for our products, which could result in production delays. While none of our products are currently the subject of retaliatory tariffs, they could be in the future, and customers in some countries or regions, such as China, may begin to seek domestic or non-U.S. sources for products that we sell, or be pressured or incentivized by foreign governments not to purchase U.S.-origin goods, which could harm our future sales in these markets. The Administration has also indicated its desire to renegotiate certain international trade agreements, which if carried out could result in additional disruptions to our supply chain.

Item 2. Unregistered sales of equity securities and use of proceeds

The Teledyne Technologies Incorporated Employee Stock Purchase Plan (the “Plan”) allows employees to purchase shares of Teledyne common stock through regular payroll deductions.  The Plan includes a 25% employer matching feature. The Plan administrator purchases shares of Teledyne common stock on the open market, and then allocates the shares to participants’ Plan accounts. In March 2018, we determined that participants in the Plan may have purchased more shares of Teledyne common stock than were registered under the Securities Act of 1933. We did not receive any consideration in connection with such purchases, which were funded with participants’ payroll deduction plus the employer match. On April 27, 2018, we filed a registration statement on Form S-8 to register future transactions by the Plan.

32

Item 5. Other Information

On August 1, 2018, Teledyne and two senior executives, including Thomas H. Reslewic, President of Teledyne’s Environmental and Electronic Measurement Instrumentation (EEMI) and Defense Electronics Groups, entered into Change in Control Severance Agreements. The Change in Control Severance Agreements, which were authorized by Teledyne’s Board with assistance from independent compensation consultants, are substantially similar to agreements entered into with Teledyne’s other named executives and certain senior executive officers. The Change in Control Severance Agreements have a three-year, automatically renewing terms. Each executive is entitled to severance benefits if (1) there is a change in control of the Company and (2) within three months before or 24 months after the change in control, either we terminate the executive’s employment for reasons other than cause or the executive terminates his employment for good reason. “Severance benefits” for each executive currently consist of:  

Ÿ	A cash payment equal to two times the sum of (i) the executive’s highest annual base salary within the year preceding the change in control and (ii) the Annual Incentive Plan bonus target for the year in which the change in control occurs or the average actual bonus payout for the three years immediately preceding the change in control, whichever is higher.
Ÿ	A cash payment for the current Annual Incentive Plan bonus cycle based on the fraction of the year worked times the Annual Incentive Plan target objectives at 100% (with payment of the prior year bonus if not yet paid).
Ÿ	Payment in cash for unpaid PSP awards, assuming applicable goals are met at 100% of performance.
Ÿ	Continued equivalent health and welfare (e.g., medical, dental, vision, life insurance and disability) benefits at our expense for a period of up to 24 after termination (with the executive bearing any portion of the cost the executive bore prior to the change in control); provided, however, such benefits would be discontinued to the extent the executive receives similar benefits from a subsequent employer.
Ÿ	Removal of restrictions on performance-based restricted stock issued under our restricted stock award programs.
Ÿ	Up to $15,000 reimbursement for actual professional outplacement services.
Ÿ	Immediate vesting of all stock options, with options being exercisable for the full remainder of the term.
Ÿ	In the event amounts under the agreements constitute an “excess parachute” payment as defined in Section 280G of the Internal Revenue Code, the executive will receive the better of, on an after-tax basis, (a) the unreduced excess parachute payment with no tax gross up payment, or (b) a parachute payment reduced to a level below which an excise tax is imposed.

For the purposes of the Change in Control Severance Agreement, a “change in control” will generally be deemed to occur if (1) the Company acquires actual knowledge that any person or group of persons acting together has acquired the beneficial ownership of securities of the Company entitling such person to 20% or more of the voting power of the Company, (2) a tender offer to acquire 20% or more of the voting power of the Company is completed, (3) a successful third party proxy solicitation is made relating to the election or removal of 50% or more of the members of the Board or any class of the Board, or (4) a merger, consolidation, share exchange, division or sale or other disposition of assets of the Company occurs as a result of which the stockholders of the Company immediately prior to such transaction do not hold, immediately following such transaction, a majority of the voting power of the surviving, acquiring or resulting corporation.

A copy of the Change in Control Severance Agreements with Mr. Reslewic (who is a named executive in Teledyne's 2018 Proxy Statement) is attached as Exhibit 10.1 to this Quarterly Report and incorporated herein by reference.

Exhibit 10.1

CHANGE IN CONTROL SEVERANCE AGREEMENT

THIS CHANGE IN CONTROL SEVERANCE AGREEMENT (“Agreement”) is made and entered into as of this 1st day of August, 2018 (the “Effective Date”), by and among Teledyne Technologies Incorporated, a Delaware corporation (hereinafter referred to as the “Company”), and Thomas Reslewic, an individual residing at the address set forth on the signature page of this Agreement (the “Executive”).

W I T N E S S E T H:

WHEREAS, the Board of Directors of the Company (the “Board”) has approved the Company entering into this Agreement providing for certain severance protection for the Executive following a Change in Control (as hereinafter defined);

WHEREAS, the Board of the Company believes that, should the possibility of a Change in Control arise, it is imperative that the Company be able to receive and rely upon the Executive’s advice, if requested, as to the best interests of the Company and its stockholders without concern that he or she might be distracted by the personal uncertainties and risks created by the possibility of a Change in Control;

WHEREAS, in addition to the Executive’s regular duties, he or she may be called upon to assist in the assessment of a possible Change in Control, advise management and the Board of the Company as to whether such Change in Control would be in the best interests of the Company and its stockholders, and to take such other actions as the Board determines to be appropriate; and

WHEREAS, the Executive believes it is in the best interest of Executive to enter into this Agreement;

NOW, THEREFORE, to assure the Company that it will have the continued dedication of the Executive and the availability of his or her advice and counsel notwithstanding the possibility, threat, or occurrence of a Change in Control, and to induce the Executive to remain in the employ of the Company, and for good and valuable consideration, and the mutual covenants set forth herein, the Company and the Executive, intending to be legally bound, agree as follows:

(f)For purposes hereof, the term “Cause” shall mean the Executive’s conviction of a felony, breach of a fiduciary duty involving personal profit to the Executive or intentional failure to perform stated duties reasonably associated with the Executive’s position; provided, however, an intentional failure to perform stated duties shall not constitute Cause unless and until the Board provides the Executive with written notice setting forth the specific duties that, in the Board’s view, the Executive has failed to perform and the Executive is provided a period of thirty (30) days to cure such specific failure(s) to the reasonable satisfaction of the Board.

(2)The Company’s requiring the Executive to be based at a location in excess of thirty-five (35) miles from the location of the Executive’s principal job location or office immediately prior to the Change in Control, except for required travel on the Company’s business to an extent substantially consistent with the Executive’s present business obligations;

(3)A reduction in the Executive’s annual salary or any material reduction by the Company of the Executive’s other compensation or benefits from that in effect on the Reference Date or on the date of the Change in Control, whichever is greater;

(4)The failure of the Company to obtain an agreement satisfactory to the Executive from any successor to the Company to assume and agree to perform the Company’s obligations under this Agreement, as contemplated in Article 5 herein; and

(5)Any purported termination by the Company of the Executive’s employment that is not effected pursuant to a Notice of Termination satisfying the requirements of Section 2.6 below, and for purposes of this Agreement, no such purported termination shall be effective.

The Executive’s right to terminate employment for Good Reason shall not be affected by the Executive’s (A) incapacity due to physical or mental illness or (B) continued employment following the occurrence of any event constituting Good Reason herein.

(l)“PSP” means the Company’s Performance Share Program as it exists on the date hereof and as it may be, amended, supplemented, or modified from time to time or any successor plan.

(m)“RSAP” means the Company’s Restricted Stock Award Program as it exists on the date hereof and as it may be, amended, supplemented or modified from time to time or any successor plan.

(n)“Separation from Service” means the cessation of Employment of the Executive or the cessation of an independent contractor relationship between the Company and the Executive (in each case to the level of interaction then permitted under regulations issued pursuant to Section 409A of the Code) or the Executive’s death, or Disability.

(o)“Severance Compensation” means two (2) times Base Compensation.

Article II.Severance Benefits

2.1Right to Severance Benefits. The Executive shall be entitled to receive from the Company severance benefits described in Section 2.2 of the Change in Control Agreement (collectively, the “Severance Benefits”) if a Change in Control shall occur and within twenty-four (24) months after the Change in Control either of the following shall occur:

(a)the Executive has a Separation from Service with the Company without Cause; or

(b)the Executive has a voluntary Separation from Service with the Company for Good Reason.

2.2Severance Benefits. In the event that the Executive becomes entitled to receive Severance Benefits, as provided in Section 2.1, the Company shall pay or provide the Accrued Obligations within thirty (30) days of the Effective Date of Termination and the Company shall provide the Executive with total Severance Benefits as follows (but subject to Sections 2.5 and 2.6) on the 409A Payment Date:

(a)The Executive shall receive a single lump sum cash Severance Compensation payment.

(b)The Executive shall receive as AIP for the year in which occurs the Effective Date of Termination a lump sum cash payment equal to that which would have been paid if corporate and personal performance had achieved 100% of target objectives established for the annual period in which the Change in Control occurred, multiplied by a fraction, the numerator of which is the number of days elapsed in the current fiscal period to the Effective Date of Termination, and the denominator of which is 365.

(c)If the Executive participates in the PSP, the Executive shall receive a lump sum payment (in accordance with the then current PSP; provided that any portion of the PSP award which would have been paid in stock under the PSP is to be paid in cash based on the current market value of the stock) which payment will be determined based upon actual performance for the number of full years of completed then current PSP measurement period(s) at the time of the Effective Date of Termination and for years not yet completed in the then current PSP measurement period(s) Executive will be assumed to have met all applicable goals at 100% of performance.

(d)All welfare benefits, including medical, dental, vision, life and disability benefits pursuant to plans under which the Executive and/or the Executive’s family is eligible to receive benefits and/or coverage shall be continued for a period of twenty-four (24) months after the Effective Date of Termination. Such benefits shall be provided to the Executive at no less than the same coverage level as in effect as of the date of the Change in Control. The Company shall pay the full cost of such continued benefits, except that the Executive shall bear any portion of such cost as was required to be borne by key executives of the Company generally at the date of the Change in Control. Notwithstanding the foregoing, the benefits described in this Section 2.2(e) may be discontinued prior to the end of the periods provided in this Section to the extent, but only to the extent, that the Executive receives substantially similar benefits from a subsequent employer. In the event any insurance carrier shall refuse to provide coverage to a former employee, the Company shall secure comparable coverage or may self-insure the benefits if it pays such benefits together with a payment to the Executive equal to the federal income tax consequences of payments to a former highly compensated employee from a discriminatory self-insured plan. If there is a cessation of coverage under the Company’s health plan between the date of the Executive’s Separation from Service and the 409A Payment Date, the Executive shall be deemed to elect COBRA coverage and the Executive shall pay the cost of COBRA coverage through the 409A Payment Date. On the 409A Payment Date, the Company shall reimburse the Executive for all COBRA costs paid by the Executive in addition to all other Severance Benefits.

(e)The Executive shall be entitled to reimbursement for actual payments made for professional outplacement services or job search not to exceed $15,000 in the aggregate.

(f)In determining the Executive’s pension benefit following entitlement to a Severance Benefit, the Executive shall be deemed to have satisfied the age and service requirements for full vesting under the Company’s qualified (within applicable legal parameters), non-qualified and supplemental

pension plans as of the Effective Date of Termination such that the Executive shall be entitled to receive the full accrued benefit under all such plans in which the Executive participates in effect as of the date of the Change in Control, without any actuarial reduction for early payment.

Notwithstanding anything in this Section 2.2 or elsewhere in this Agreement to the contrary, if counsel to the Company determines in good faith that the Severance Benefits set forth in this Agreement are not subject to an increase in federal income tax liability to the Executive under Section 409A of the Code or the Executive is not a specified employee for purposes of Section 409A of the Code at such Executive’s termination of employment, all elements of the Severance Benefits shall be paid or commenced, as applicable, within thirty (30) days after such Executive’s Effective Date of Termination.

2.3Stock Options. In the event of entitlement to a Severance Benefit, all Company stock options previously granted to the Executive shall be fully vested and exercisable immediately. Such options shall be exercisable for the remainder of the term established by the Company’s stock option plan as if the options had vested in accordance with the normal vesting schedule and the Executive had remained an employee of the Company. Company stock acquired pursuant to any such exercise may be sold by the Executive free of any Company restrictions, whatsoever (other than those imposed by federal and state securities laws).

2.4RSAP. In the event of entitlement to a Severance Benefit, all forfeiture restrictions on all Company stock issued to the Executive under the Company’s RSAP shall lapse and all shares of restricted stock shall vest. All of the foregoing shares may be sold by the Executive free of any Company restrictions whatsoever (other than those imposed by federal and state securities laws).

2.5Termination for any Other Reason. If the Executive’s employment with the Company is terminated under any circumstances other than those set forth in Section 2.1, including without limitation by reason of retirement, death, disability, discharge for Cause or resignation without Good Reason, or any termination, for any reason, that occurs prior to a Change in Control (other than as provided below) or after twenty-four (24) months following a Change in Control, the Executive shall have no right to receive the Severance Benefits under this Agreement or to receive any payments in respect of this Agreement. In such event Executive’s benefits, if any, in respect of such termination shall be determined in accordance with the Company’s retirement, survivor’s benefits, insurance, and other applicable plans, programs, policies and practices then in effect. Notwithstanding anything in this Agreement to the contrary, if the Executive’s employment with the Company is terminated at any time from three (3) to eight (8) months prior to the date on which a Change in Control occurs either (i) by the Company other than for Cause or (ii) by the Executive for Good Reason, and it is reasonably demonstrated that termination of employment (a) was at the request of an unrelated third party who has taken steps reasonably calculated to effect a Change in Control, or (b) otherwise arose in connection with or in anticipation of the Change in Control, then for all purposes of this Agreement the termination shall be deemed to have occurred as if immediately following a Change in Control for Good Reason and the Executive shall be entitled to Severance Benefits as provided in Section 2.2 hereof. Notwithstanding anything in this Agreement to the contrary, if the Executive’s employment with the Company is terminated at any time within three (3) months prior to the date on which a Change in Control occurs either (i) by the Company other than for Cause or (ii) by the Executive for Good Reason, such termination shall conclusively be deemed to have occurred as if immediately following a Change in Control for Good Reason and the Executive shall be entitled to Severance Benefits as provided in Section 2.2 hereof.

2.6Notice of Termination. Any termination by the Company for Cause or by the Executive for Good Reason shall be communicated by Notice of Termination to the other party. For purposes of this Agreement, a “Notice of Termination” shall mean a written notice which shall indicate the specific

termination provision in this Agreement relied upon, and shall set forth in reasonable detail the facts and circumstances claimed to provide a basis for termination of the Executive’s employment under the provision so indicated.

2.7Withholding of Taxes. The Company shall withhold from any amounts payable under this Agreement all Federal, state, local, or other taxes that are legally required to be withheld.

2.8Limitation on Payments.

(a)    Notwithstanding any other provisions of this Agreement, in the event that any payment or benefit received or to be received by the Executive (including any payment or benefit received in connection with a Change in Control or the termination of the Executive’s employment with the Company, whether pursuant to the terms of this Agreement or any other plan, arrangement or agreement) (all such payments and benefits, being hereinafter referred to as the “Total Payments”) would be subject (in whole or part), to the excise tax imposed under Section 4999 of the Code (the “Excise Tax”), then, after taking into account any reduction in the Total Payments provided by reason of Section 280G of the Code in such other plan, arrangement or agreement, the Total Payments shall be reduced in the order specified below, to the extent necessary so that no portion of the Total Payments is subject to the Excise Tax but only if (i) the net amount of such Total Payments, as so reduced (and after subtracting the net amount of federal, state and local income taxes on such reduced Total Payments and after taking into account the phase out of itemized deductions and personal exemptions attributable to such reduced Total Payments) is greater than or equal to (ii) the net amount of such Total Payments without such reduction (but after subtracting the net amount of federal, state and local income taxes on such Total Payments and the amount of Excise Tax to which the Executive would be subject in respect of such unreduced Total Payments and after taking into account the phase out of itemized deductions and personal exemptions attributable to such unreduced Total Payments). The Total Payments shall be reduced by the Company in its reasonable discretion in the following order: (A) reduction of any cash severance payments otherwise payable to the Executive that are exempt from Section 409A of the Code, other than payments that are subject to Q/A 24(c) of Treas. Reg. Sec. 1.280G)-1, (B) reduction of any other cash payments or benefits otherwise payable to the Executive that are exempt from Section 409A of the Code, other than payments that are subject to Q/A 24(c) of Treas. Reg. Sec. 1.280G)-1, (C) reduction of any other payments or benefits otherwise payable to the Executive, other than payments that are subject to Q/A 24(c) of Treas. Reg. Sec. 1.280G)1 and (D) reduction of any payments that are subject to Q/A 24(c) of Treas. Reg. Sec. 1.280G). The reduction of any payments that are subject to Section 409A of the Code shall be made on a pro-rata basis or such other manner that complies with Section 409A of the Code.

(b)    All determinations required to be made under this Section 2.8 shall be made by the Company’s regular outside independent public accounting firm (the “Accounting Firm”) which shall provide detailed supporting calculations both to the Company and the Executive within fifteen (15) business days of the Effective Date of Termination, if applicable, or such earlier time as is requested by the Company

(c)    For purposes of determining whether and the extent to which the Total Payments will be subject to the Excise Tax, (i) no portion of the Total Payments the receipt or enjoyment of which the Executive shall have waived at such time and in such manner as not to constitute a “payment” within the meaning of Section 280G(b) of the Code shall be taken into account, (ii) no portion of the Total Payments shall be taken into account which, in the opinion of Accounting Firm does not constitute a “parachute payment” within the meaning of Section 280G(b)(2) of the Code (including by reason of Section 280G(b)(4)(A) of the Code) and, in calculating the Excise Tax, no portion of such Total Payments shall be taken into account which, in the opinion of Accounting Firm, constitutes reasonable compensation for services actually rendered, within the meaning of Section 280G(b)(4)(B) of the Code, in excess of the Base

Amount (as defined in Section 280G(b)(3) of the Code) allocable to such reasonable compensation, and (iii) the value of any noncash benefit or any deferred payment or benefit included in the Total Payments shall be determined by the Accounting Firm in accordance with the principles of Sections 280G(d)(3) and (4) of the Code.

Article III.The Company’s Payment Obligation

3.1Payment Obligations Absolute. Except as otherwise provided in the last sentence of Section 2.2(e), the Company’s obligation to make the payments and the arrangements provided for in this Agreement shall be absolute and unconditional, and shall not be affected by any circumstances, including, without limitation, any offset, counterclaim, recoupment, defense, or other right that the Company may have against the Executive or any other party. All amounts payable by the Company under this Agreement shall be paid without notice or demand. Each and every payment made hereunder by the Company shall be final, and the Company shall not seek to recover all or any part of such payment from the Executive or from whomsoever may be entitled thereto, for any reasons whatsoever. Notwithstanding any other provisions of this Agreement to the contrary, the Company shall have no obligation to make any payment to the Executive hereunder to the extent, but only to the extent, that such payment is prohibited by the terms of any final order of a Federal or state court or regulatory agency of competent jurisdiction; provided, however, that such an order shall not affect, impair, or invalidate any provision of this Agreement not expressly subject to such order.

3.2Contractual Rights to Payments and Benefits. This Agreement establishes and vests in the Executive a contractual right to the payments and benefits to which he or she is entitled hereunder. Nothing herein contained shall require or be deemed to require, or prohibit or be deemed to prohibit, the Company to segregate, earmark, or otherwise set aside any funds or other assets, in trust or otherwise, to provide for any payments to be made or required hereunder. The Executive shall not be obligated to seek other employment in mitigation of the amounts payable or arrangements made under any provision of this Agreement, and the obtaining of any such other employment shall in no event effect any reduction of the Company’s obligations to make the payments and arrangements required to be made under this Agreement, except to the extent provided in the last sentence of Section 2.2(e).

Article IV.Enforcement and Legal Remedies

4.1Consent to Jurisdiction. Each of the parties hereto irrevocably consents to personal jurisdiction in any action brought in connection with this Agreement in the United States District Court for the Central District of California or any California court of competent jurisdiction. The parties also consent to venue in the above forums and to the convenience of the above forums. Any suit brought to enforce the provisions of this Agreement must be brought in the aforementioned forums.

4.2Cost of Enforcement. In the event that it shall be necessary or desirable for the Executive to retain legal counsel in connection with the enforcement of any or all of his or her rights to Severance Benefits under Section 2.2 of this Agreement, and provided that the Executive substantially prevails in the enforcement of such rights, the Company, as applicable, shall pay (or the Executive shall be entitled to recover from the Company, as the case may be) the Executive’s reasonable attorneys’ fees, costs and expenses in connection with the enforcement of his or her rights.

Article V.Binding Effect; Successors

The rights of the parties hereunder shall inure to the benefit of their respective successors, assigns, nominees, or other legal representatives. The Company shall require any successor (whether direct or

indirect, by purchase, merger, reorganization, consolidation, acquisition of property or stock, liquidation, or otherwise) to all or a significant portion of the assets of the Company, as the case may be, by agreement in form and substance reasonably satisfactory to the Executive, expressly to assume and agree to perform this Agreement in the same manner and to the same extent that the Company, as the case may be, would be required to perform if no such succession had taken place. Regardless of whether such agreement is executed, this Agreement shall be binding upon any successor in accordance with the operation of law and such successor shall be deemed the “Company”, as the case may be, for purposes of this Agreement.

Article VI.Term of Agreement

The term of this Agreement shall commence on the Effective Date and shall continue in effect for three (3) full years (the “Term”) unless further extended as provided in this Article. The Term of this Agreement shall be automatically and without action by either party extended for one additional calendar month on the last business day of each calendar month so that at any given time there are no fewer than 35 nor more than 36 months remaining unless one party gives written notice to the other that it no longer wishes to extend the Term of this Agreement, after which written notice, the Term shall not be further extended except as may be provided in the following sentence. However, in the event a Change in Control occurs during the Term, this Agreement will remain in effect for the longer of: (i) thirty-six (36) months beyond the month in which such Change in Control occurred; or (ii) until all obligations of the Company hereunder have been fulfilled and all benefits required hereunder have been paid to the Executive or other party entitled thereto.

7.3Entire Agreement. This Agreement contains the entire understanding of the Company and the Executive with respect to the subject matter hereof.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

General

General

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements have been prepared by Teledyne Technologies Incorporated (“Teledyne” or the “Company”) pursuant to the rules and regulations of the Securities and Exchange Commission. Certain information and disclosures normally included in notes to consolidated financial statements have been condensed or omitted pursuant to such rules and regulations, but resultant disclosures are in accordance with accounting principles generally accepted in the United States (“GAAP”) as they apply to interim reporting. The condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and the related notes in Teledyne’s Annual Report on Form 10-K for the fiscal year ended December 31, 2017 (“2017 Form 10-K”).

In the opinion of Teledyne’s management, the accompanying unaudited condensed consolidated financial statements contain all adjustments (consisting of normal recurring adjustments) necessary to present fairly, in all material respects, Teledyne’s consolidated financial position as of July 1, 2018 and the consolidated results of operations, consolidated comprehensive income or the three and six months then ended and cash flows for the six months then ended. The results of operations and cash flows for the period ended July 1, 2018 are not necessarily indicative of the results of operations or cash flows to be expected for any subsequent quarter or the full fiscal year. Certain prior year amounts have been reclassified to conform to the current period presentation.

In the second quarter of 2018, we realigned the reporting structure for certain of our microwave product groupings. These products, acquired with the acquisition of e2v were formerly reported as part of the Aerospace and Defense Electronics segment and are now reported as part of the Digital Imaging segment. Previously reported segment data has been adjusted to reflect this change. Total sales for these products were $24.2 million for fiscal year 2017.

Recent Accounting Pronouncements

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). The new guidance will require lessees to recognize most leases on their balance sheet as a right-of-use asset and a lease liability, other than leases that meet the definition of a short-term lease. For income statement purposes, the FASB retained a dual model, requiring leases to be classified as either operating or finance. The new guidance is effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years, with early adoption permitted. The new guidance can be adopted using either a modified retrospective transition, requiring application at the beginning of the earliest comparative period presented or a transition method whereby companies could continue to apply existing lease guidance during the comparative periods and apply the new lease requirements through a cumulative-effect adjustment in the period of adoption rather than in the earliest period presented without adjusting historical financial statements. We plan to adopt the new standard on December 31, 2018, the beginning of our 2019 fiscal year, and are currently evaluating the impact this guidance will have on the consolidated financial statements, including the selection of a transition method, and footnote disclosures. Please refer to Note 13 of the Notes to Consolidated Financial Statements included in our 2017 Form 10-K for additional information about the Company’s leases, including the future minimum lease payments of the Company’s operating leases at December 31, 2017.

In February 2018, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2018-02, “Income Statement-Reporting Comprehensive Income (Topic 220) Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income”, to address a specific consequence of the Tax Cuts and Jobs Act (“Tax Act”) by allowing a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Act reduction of the U.S. federal corporate income tax rate.  The guidance is effective for all entities for annual periods beginning after December 15, 2018, with early adoption permitted, and is to be applied either in the period of adoption or retrospectively to each period in which the effect of the change in the U.S. federal corporate income tax rate in the Tax Act is recognized.   Teledyne is currently evaluating the impact this guidance will have on the consolidated financial statements and footnote disclosures.

In August 2017, the FASB issued ASU No. 2017-12, “Derivatives and Hedging (Topic 815) Targeted Improvements to Accounting for Hedging Activities.” This ASU better aligns an entity’s risk management activities and financial reporting for hedging relationships. This ASU expands and refines hedge accounting for both nonfinancial and financial risk components, and this ASU simplifies and aligns the recognition and presentation of the effects of the hedging instrument and the hedged item in the financial statements. This ASU is effective for fiscal years beginning after December 15, 2018 and for interim periods therein, with early adoption permitted. Teledyne is currently evaluating the impact this guidance will have on the consolidated financial statements and footnote disclosures.

In January 2017, the FASB issued ASU 2017-04, Simplifying the Test for Goodwill Impairment, which eliminates the computation of the implied fair value of goodwill to measure a goodwill impairment charge. Instead, entities will record a goodwill impairment charge based on the excess of a reporting unit’s carrying amount over its fair value. The new standard is effective for interim and annual reporting periods beginning after December 15, 2019, with early adoption permitted. We expect the adoption of this standard will reduce the complexity surrounding the evaluation of goodwill for impairment. The impact of this new standard for the Company will depend on the outcomes of future goodwill impairment tests.

In May 2014, the FASB issued ASU No. 2014-09 (Topic 606), Revenue from Contracts with Customers, which provides a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and superseded most current revenue recognition guidance under Topic 605, Revenue Recognition. Under the new standard, an entity recognizes revenue when or as it satisfies a performance obligation by transferring control of a good or service to the customer, either at a point in time or over time. The new standard requires expanded disclosures, including how and when we satisfy performance obligations as well as additional disaggregated revenue information to be provided more frequently in the reporting process.

In March 2017, the FASB issued ASU No. 2017-07, “Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost.” This ASU requires the service cost component of net benefit costs to be disaggregated from all other components and be reported in the same line item or items as other compensation costs and allow only the service cost component to be eligible for capitalization when applicable. The other components of net benefit cost are required to be presented in the income statement separately from the service cost component and before income from operations. The Company adopted the requirements of this ASU as of January 1, 2018 on a retrospective basis. As such, the Company reclassified $2.9 million and $0.5 million from cost of sales and selling, general and administrative expenses, respectively to non-service retirement benefit income for the three months ended July 2, 2017 and reclassified $5.7 million and $1.0 million from cost of sales and selling, general and administrative expenses, respectively to non-service retirement benefit income for the six months ended July 2, 2017 to conform to current period presentation.

The Company adopted the requirements of Topic 606 as of January 1, 2018, using the modified retrospective transition method which required a cumulative-effect adjustment as of the date of adoption. Adoption of Topic 606 primarily impacted contracts for which revenue prior to fiscal year 2018 was recognized using the percentage of completion (“POC”), units-of-delivery or milestone methods, as these contracts are now recognized primarily using the POC cost-to-cost method to depict the transfer of control of the good or service to the customer as the work on the contract is performed. Also, to a much lesser extent, certain contracts for customized goods and services, certain products sold to the U.S. Government, and product repair contracts are now recognized over time, as control of the good or service produced transfers to the customer over time in accordance with the guidance in Topic 606. For impacted contracts that were in process at December 31, 2017, we calculated the difference in the life to date revenue (and related costs and expenses) between legacy accounting standards and Topic 606, with the cumulative effect of initially applying Topic 606 as an adjustment to the opening balance of retained earnings, as shown below. The prior year comparative information has not been restated and continues to be reported under the accounting standards in effect for those periods. While Topic 606 includes additional disclosures, as discussed within these Notes to the Condensed Consolidated Financial Statements, comparative disclosures with prior periods are not required in the year of adoption due to our use of the modified retrospective transition method.

The cumulative effect of the changes made to our consolidated January 1, 2018 balance sheet for the adoption ofTopic 606 were as follows (in millions):

	Balance at December 31, 2017		Topic ASC 606 Adjustments		Balance at January 1, 2018

Significant Accounting Policies Update

Our significant accounting policies are detailed in “Note 2: Summary of Significant Accounting Policies” of our Annual Report on Form 10-K for the year ended December 31, 2017. Significant changes to our accounting policies as a result of adopting Topic 606 are discussed below.

Revenue Recognition

We determine the appropriate method by which we recognize revenue by analyzing the nature of the products or services being provided as well as the terms and conditions of contracts or arrangements entered into with our customers. We account for a contract when it has approval and commitment from both parties, the rights of the parties are identified, payment terms are identified, the contract has commercial substance and collectability of consideration is probable. A contract’s transaction price is allocated to each distinct good or service (i.e., performance obligation) identified in the contract, and each performance obligation is valued based on its estimated relative standalone selling price. For standard products or services, list prices generally represent the standalone selling price. For performance obligations where list price is not available, we typically use the expected cost plus a margin approach to estimate the standalone selling price for that performance obligation. Approximately 60% of our revenue is recognized at a point in time, with the remaining 40% recognized over time.

Revenue recognized at a point in time relates primarily to the sale of standard or minimally customized products, with control transferring to the customer generally upon the transfer of title. This type of revenue arrangement is typical for our commercial contracts within the Instrumentation, Digital Imaging, and Aerospace and Defense Electronics segments, and to a lesser extent for certain commercial contracts within the Engineered Systems segment relating to the sale of standard hydrogen/oxygen gas generators. In limited circumstances, customer specified acceptance criteria exist. If we cannot objectively demonstrate that the product meets those specifications prior to the shipment, the revenue is deferred until customer acceptance is obtained. Performance obligations recognized at a point in time can include variable consideration, such as product returns and sales allowances. The estimation of this variable consideration and determination of whether to include estimated amounts as a reduction in the transaction price is based largely on an assessment of our anticipated performance and all information (historical, current and forecasted) that is reasonably available to us.

Revenue recognized over time relates primarily to contracts to design, develop and/or manufacture highly engineered products used in both defense and commercial applications. This type of revenue arrangement is typical of our U.S. government contracts and to a lesser extent for certain commercial contracts, with both contract types occurring across all segments. The customer typically controls the work in process as evidenced either by contractual termination clauses or by our right to payment for costs incurred to date plus a reasonable profit for products or services that do not have an alternative use. As control transfers continuously over time on these contracts, revenue is recognized based on the extent of progress towards completion of the performance obligation. The selection of the method to measure progress towards completion requires judgment and is based on the nature of the products or services to be provided. We generally use the cost-to-cost measure of progress as this measure best depicts the transfer of control to the customer which occurs as we incur costs on our contracts. Under the cost-to-cost method, the extent of progress towards completion is measured based on the ratio of costs incurred to date to the total estimated costs at completion of the performance obligation. The transaction price in these arrangements may include estimated amounts of variable consideration, including award fees, incentive fees, or other provisions that can either increase or decrease the transaction price. We estimate variable consideration at the amount to which we expect to be entitled, and we include estimated amounts in the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur when the estimation uncertainty is resolved. The estimation of this variable consideration and determination of whether to include estimated amounts in the transaction price are based largely on an assessment of our anticipated performance and all information (historical, current and forecasted) that is reasonably available to us.

The majority of our over time contracts have a single performance obligation as the promise to transfer the individual goods or services is not separately identifiable from other promises in the contracts and, therefore, not distinct. Over time contracts are often modified to account for changes in contract specifications and requirements. We consider contract modifications to exist when the modification either creates new or changes the existing enforceable rights and obligations. Most of our contract modifications on over time contracts are for goods or services that are not distinct from the existing contract due to the significant integration service provided in the context of the contract and are accounted for as if they were part of that existing contract. The effect of a contract modification on the transaction price and our measure of progress for the performance obligation to which it relates, is recognized as an adjustment to revenue (either as an increase in or a reduction of revenue) on a cumulative catch-up basis.

For over time contracts using cost-to-cost, we have an Estimate at Completion (“EAC”) process in which management reviews the progress and execution of our performance obligations. This EAC process requires management judgment relative to assessing risks, estimating contract revenue and cost, and making assumptions for schedule and technical issues. This EAC process requires management’s judgment to make reasonably dependable cost estimates. Since certain contracts extend over a longer period of time, the impact of revisions in cost and revenue estimates during the progress of work may adjust the current period earnings through a cumulative catch-up basis. This method recognizes, in the current period, the cumulative effect of the changes on current and prior quarters. Additionally, if the current contract estimate indicates a loss, a provision is made for the total anticipated loss in the period that it becomes evident. Contract cost and revenue estimates for significant contracts are generally reviewed and reassessed quarterly. The majority of revenue recognized over time uses an EAC process. The net aggregate effects of these changes in estimates on contracts accounted for under the cost-to-cost method in the first six months of 2018 was less than $0.1 million of unfavorable revenue and operating income. None of the effects of changes in estimates on any individual contract were material to the condensed consolidated statements of income for any period presented.

While extended or non-customary warranties do not represent a significant portion of our revenue, we recognize warranty services as a separate performance obligations when it is material to the contract. When extended or non-customary warranties represents a separate performance obligation, the revenue is deferred and recognized ratably over the extended warranty period.

The timing of revenue recognition, billings and cash collections results in billed accounts receivable, unbilled receivables (contract assets), and customer advances and deposits (contract liabilities, which are included in accrued liabilities and other long-term liabilities) on the Condensed Consolidated Balance Sheet. Under the typical payment terms of our over time contracts, the customer pays us either performance-based payments or progress payments. Amounts billed and due from our customers are classified as receivables on the Condensed Consolidated Balance Sheet. We may receive interim payments as work progresses, although for some contracts, we may be entitled to receive an advance payment. We recognize a liability for these interim and advance payments in excess of revenue recognized and present it as a contract liability which is included within accrued liabilities and other long-term liabilities on the Condensed Consolidated Balance Sheet, which represented $101.6 million and $14.0 million as of July 1, 2018, and $110.3 million and $15.5 million as of January 1, 2018, respectively. Contract liabilities typically are not considered a significant financing component because these cash advances are used to meet working capital demands that can be higher in the early stages of a contract, and these cash advances protect us from the other party failing to adequately complete some or all of its obligations under the contract. When revenue recognized exceeds the amount billed to the customer, we record an unbilled receivable (contract asset) for the amount we are entitled to receive based on our enforceable right to payment. The unbilled receivable balance increased from the beginning of the year by $36.5 million, or 30.7%, primarily due to work performed ahead of billings on certain over time revenue contracts primarily in our Aerospace and Defense Electronics operating segment. Contract liabilities decreased from the beginning of the year by $10.3 million, or 8.1%, primarily due to the recognition of revenue in the year on customer advances that existed at the beginning of the year. The Company recognized revenue of $48.6 million during the quarter ended July 1, 2018 from contract liabilities that existed at the beginning of year. The Company recognizes the incremental costs of obtaining or fulfilling a contract as expense when incurred if the amortization period of the asset is one year or less. Incremental costs to obtain or fulfill contracts with an amortization period greater than one year were not material.

Remaining performance obligations represent the transaction price of firm orders for which work has not been performed as of the period end date and excludes unexercised contract options and potential orders under ordering-type contracts (e.g., indefinite-delivery, indefinite-quantity). As of July 1, 2018, the aggregate amount of the transaction price allocated to remaining performance obligations was $1,632.6 million. The Company expects approximately 83% of remaining performance obligations to be recognized into revenue within the next twelve months, with the remaining 17% recognized thereafter.

Business Combinations, Goodwill and Acquired Intangible Assets

Acquisition of e2v

On March 28, 2017, Teledyne completed the acquisition of all of the outstanding common stock of e2v technologies plc (“e2v”) for $770.7 million, including stock options and assumed debt, net of $24.4 million of cash acquired. Principally located in Chelmsford, United Kingdom and Grenoble, France, most of e2v’s operations are included in the Digital Imaging and Aerospace and Defense Electronics segments. The Instrumentation segment includes a small portion of e2v’s operations.

The first six months of 2017 includes pretax charges of $25.2 million related to the acquisition of e2v, which included $12.8 million in transaction costs, including stamp duty, advisory, legal and other consulting fees and other costs recorded to selling, general and administrative expenses, $4.1 million in inventory fair value step-up amortization expense recorded to cost of sales, $2.3 million in bank bridge facility commitment expense recorded to interest expense and $6.0 million related to a foreign currency option contract expense to hedge the e2v purchase price recorded as other expense. Of these amounts, $6.5 million impacted segment operating income.

The unaudited proforma information below, as required by GAAP, assumes that e2v had been acquired at the beginning of the 2017 fiscal year and includes the effect of increased interest expense on net acquisition debt and the amortization of acquired intangible assets. The 2017 proforma amount also include $12.3 million in transaction costs, including legal and other consulting fees, $11.5 million in expense related to a foreign currency option contract to hedge the e2v purchase price, $2.8 million in bridge financing costs and $1.4 million in inventory fair value step-up amortization expense. These amounts totaling $28.0 million should be considered non-recurring costs that were necessary to complete the acquisition and are not indicative of the ongoing operations of the combined company.

This unaudited proforma financial information is presented for informational purposes only and is not necessarily indicative of the results of operations that actually would have resulted had the acquisition been in effect at the beginning of the periods presented. In addition, the unaudited proforma results are not intended to be a projection of future results and do not reflect any operating efficiencies or cost savings that might be achievable.

The following table presents proforma net sales, net income and earnings per share data assuming e2v was acquired at the beginning of the 2017 fiscal year:

	Second Quarter (a)		Six Months (a)
(unaudited - in millions, except per share amounts)	2017		2017

Diluted earnings per common share	$	1.66	$	2.02

a) The above unaudited proforma information is presented for the e2v acquisition as it is considered a material acquisition.

SSI Acquisition

On July 20, 2017, a subsidiary of Teledyne acquired assets of Scientific Systems, Inc. (“SSI”) for $31.0 million in cash. Headquartered in State College, PA, SSI is part of the Instrumentation segment.

For a further description of the Company’s acquisition activity for fiscal year 2017, please refer to Note 3 of the Notes to Consolidated Financial Statements included in our 2017 Form 10-K.

Goodwill and Acquired Intangible Assets

Teledyne’s goodwill was $1,758.9 million at July 1, 2018 and $1,776.7 million at December 31, 2017. The decrease in the balance of goodwill in 2018 included the impact of exchange rate changes, partially offset by adjustments for the purchase accounting allocation for the e2v and SSI acquisitions. Teledyne’s net acquired intangible assets were $368.6 million at July 1, 2018 and $398.9 million at December 31, 2017. The decrease in the balance of net acquired intangible assets reflected amortization and the impact of exchange rate changes, partially offset by adjustments for the purchase accounting allocation for the SSI acquisition. The Company completed the process of specifically identifying the amount to be assigned to certain assets, including acquired intangible assets, and liabilities and the related impact on taxes and goodwill for the e2v and SSI acquisitions, including the allocation by segment, resulting in an increase to goodwill of $3.9 million for e2v and $4.8 million for SSI in 2018.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivative Instruments

Derivative Instruments

Teledyne transacts business in various foreign currencies and has international sales and expenses denominated in foreign currencies, subjecting the Company to foreign currency risk. The Company’s primary foreign currency risk management objective is to protect the US dollar value of future cash flows and minimize the volatility of reported earnings. All derivatives are recorded on the balance sheet at fair value. As discussed below, the accounting for gains and losses resulting from changes in fair value depends on the use of the derivative and whether it is designated and qualifies for hedge accounting. The Company utilizes foreign currency forward contracts to reduce the volatility of cash flows primarily related to forecasted revenues and expenses denominated in Canadian dollars for our Canadian companies, including DALSA and in British pounds for our UK companies, including e2v. These contracts are designated and qualify as cash flow hedges. The Company has converted a US dollar denominated, variable rate debt obligation into a euro fixed rate obligation using a receive-float, pay fixed cross currency swap. This cross currency swap is designated as a cash flow hedge.

Cash Flow Hedging Activities

The effectiveness of the forward contract cash flow hedge, which exclude time value, and the cross currency swap cash flow hedge is assessed prospectively and retrospectively on a monthly basis using regression analysis, as well as using other timing and probability criteria. To receive hedge accounting treatment, all hedging relationships are formally documented at the inception of the hedges and must be highly effective in offsetting changes to future cash flows on hedged transactions. The effective portion of the cash flow hedge forward contracts’ gains or losses resulting from changes in the fair value of these hedges is initially reported, net of tax, as a component of AOCI in stockholders’ equity until the underlying hedged item is reflected in our consolidated statements of income, at which time the effective amount in AOCI is reclassified to cost of sales in our consolidated statements of income. For the cross currency swap cash flow hedge, effective amounts are recorded in AOCI, and reclassified into interest expense in the consolidated statements of income. In addition, for the cross currency swap an amount is reclassified from AOCI to other income and expense each reporting period, to offset the earnings impact of the remeasurement of the hedged liability. Net deferred losses recorded in AOCI, net of tax, for the forward contracts that will mature in the next twelve months total $0.3 million. These losses are expected to be offset by anticipated gains in the value of the forecasted underlying hedged item. Amounts related to the cross currency swap expected to be reclassified from AOCI into income in the coming twelve months total $2.8 million.

In the event that the gains or losses in AOCI are deemed to be ineffective, the ineffective portion of gains or losses resulting from changes in fair value, if any, is reclassified to other income and expense. In the event that the underlying forecasted transactions do not occur, or it becomes remote that they will occur, within the defined hedge period, the gains or losses on the related cash flow hedges will be reclassified from AOCI to other income and expense. During the current reporting period, all forecasted transactions occurred and, therefore, there were no such gains or losses reclassified to other income and expense. As of July 1, 2018, Teledyne had foreign currency forward contracts designated as cash flow hedges to buy Canadian dollars and to sell U.S. dollars totaling $102.4 million. These foreign currency forward contracts have maturities ranging from September 2018 to February 2020. Together the contracts had a negative fair value of $2.1 million. The cross currency swap has notional amounts of €93.0 million equivalent to $100.0 million, and matures in October 2019.

The effect of derivative instruments designated as cash flow hedges in the condensed consolidated financial statements for the second quarter ended July 1, 2018 and July 2, 2017 was as follows (in millions):

	Second Quarter						Six Months
	2018			2017			2018			2017

a)    Effective portion, pre-tax

b)     Amount reclassified to offset earnings impact of liability hedged by cross currency swap

c)     Amount excluded from effectiveness testing

Non-Designated Hedging Activities

In addition, the Company utilizes foreign currency forward contracts to mitigate foreign exchange rate risk associated with foreign-currency-denominated monetary assets and liabilities, including intercompany receivables and payables. As of July 1, 2018, Teledyne had non-designated foreign currency contracts of this type in the following pairs (in millions):

Contracts to Buy			Contracts to Sell
Currency	Amount		Currency	Amount
Canadian Dollars	C$	211.2	U.S. Dollars	US$	162.8
Canadian Dollars	C$	15.1	Euros	€	9.9
Euros	€	55.0	Great Britain Pounds	£	48.5

U.S. Dollars	US$	0.9	Japanese Yen	¥	100.0
Danish Krone	DKR	45.5	U.S. Dollars	US$	7.2

The above table includes non-designated hedges derived from terms contained in triggered or previously designated cash flow hedges. The gains and losses on these derivatives which are not designated as hedging instruments are intended to, at a minimum, partially offset the transaction gains and losses recognized in earnings. Teledyne does not use foreign currency forward contracts for speculative or trading purposes.

The effect of derivative instruments not designated as cash flow hedges recognized in other income and expense for the second quarter and six months ended July 1, 2018 was expense of $17.0 million and $17.8 million, respectively. The effect of derivative instruments not designated as cash flow hedges in other income and expense for the second quarter and six months ended July 2, 2017 was expense of $0.5 million and $6.5 million, respectively. These losses were largely offset by gains in the value of the underlying hedged item.

Fair Value of Derivative Financial Instruments

The Company has elected to use the income approach to value the derivatives, using observable Level 2 market expectations at measurement date and standard valuation techniques to convert future amounts to a single present amount. Level 2 inputs for the valuations are limited to quoted prices for similar assets or liabilities in active markets (specifically futures contracts on LIBOR and EURIBOR) and inputs other than quoted prices that are observable for the asset or liability (specifically LIBOR and EURIBOR cash and swap rates, foreign currency forward rates and cross currency basis spreads). Mid-market pricing is used as a practical expedient for fair value measurements. The fair value measurement of an asset or liability must reflect the nonperformance risk of the entity and the counterparty. Therefore, the impact of the counterparty’s creditworthiness when in an asset position and the Company’s creditworthiness when in a liability position has also been factored into the fair value measurement of the derivative instruments and did not have a material impact on the fair value of these derivative instruments. Both the counterparty and the Company are expected to continue to perform under the contractual terms of the instruments.

The fair values of the Company’s derivative financial instruments are presented below. All fair values for these derivatives were measured using Level 2 information as defined by the accounting standard hierarchy (in millions):

Asset/(Liability) Derivatives	Balance sheet location	July 1, 2018			December 31, 2017

Stock-Based Compensation Plans

Stock-Based Compensation Plans

Teledyne has long-term incentive plans pursuant to which it has granted non-qualified stock options, restricted stock and performance shares to certain employees. The Company also has non-employee Board of Director stock compensation plans, pursuant to which non-qualified stock options and common stock, and beginning in 2015 restricted stock units, have been issued to its directors. After 2014, non-employee directors no longer receive non-qualified stock options.

Stock Incentive Plan

The following disclosures are based on stock options granted to Teledyne’s employees and directors. Stock option compensation expense was $5.4 million for the second quarter of 2018 and was $3.7 million for the second quarter of 2017. Stock option compensation expense was $10.3 million for the first six months of 2018 and was $7.8 million for the first six months of 2017. Employee stock option grants are charged to expense evenly over the three year vesting period. For 2018, the Company currently expects approximately $21.1 million in stock option compensation expense based on stock options currently outstanding. This amount can be impacted by employee retirements and terminations or stock options granted during the remainder of the year. The Company issues shares of common stock upon the exercise of stock options.

The following assumptions were used in the valuation of stock options granted in 2018:

	2018
Expected volatility	31.0%
Risk-free interest rate range	1.99% to 2.58%
Expected life in years	6.8
Expected dividend yield	—

Based on the assumptions used in the valuation of stock options, the grant date weighted average fair value of stock options granted in 2018 was $71.79 per share.

Stock option transactions for the second quarter and six months ended July 1, 2018 are summarized as follows:

Inventories

Inventories

Inventories are stated at current cost net of reserves for excess, slow moving and obsolete inventory, less progress payments. Inventories are valued under the FIFO method, LIFO method and average cost method. Inventories at cost determined on the average cost or the FIFO methods were $342.4 million at July 1, 2018 and $348.6 million at December 31, 2017. The remainder of the inventories using the LIFO method were $46.9 million at July 1, 2018 and $63.6 million at December 31, 2017. Interim LIFO calculations are based on the Company’s estimates of expected year-end inventory levels and costs since an actual valuation of inventory under the LIFO method can be made only at the end of each year based on the inventory levels and costs at that time. Because these estimates are subject to many factors beyond the Company’s control, interim results are subject to the final year-end LIFO inventory valuation.

Income Tax Disclosure [Abstract]

Income Taxes

Income Taxes

The income tax provision is calculated using an estimated annual effective tax rate, based upon expected annual income, permanent items, statutory rates and planned tax strategies in the various jurisdictions in which the Company operates. However, losses in certain jurisdictions and discrete items, such as the resolution of uncertain tax positions, are treated separately.

On December 22, 2017, the Tax Cuts and Jobs Act of 2017 (“Tax Act”) was enacted. The Tax Act significantly revised the U.S. corporate income tax by, among other things, lowering corporate income tax rates, implementing the territorial tax system and imposing a repatriation tax on deemed repatriated earnings of foreign subsidiaries. As a result of the Tax Act, Teledyne incurred provisional charges of $4.7 million in the fourth quarter of 2017 primarily due to the repatriation tax and the remeasurement of U.S. deferred tax assets and liabilities. The impacts of the Tax Act may differ from this estimate, possibly materially (and the amount of the provisional charge may accordingly be adjusted over the course of 2018), due to changes in interpretations and assumptions Teledyne has made, guidance that may be issued, and actions Teledyne may take as a result of the Tax Act. In the first quarter of 2018, the provisional charge was adjusted by an additional $0.6 million.

The Company’s effective income tax rate for the second quarter and first six months of 2018 was 17.7% and 18.3%, respectively. The Company’s effective income tax rate for the second quarter and first six months of 2017 was 21.3% and 22.6%, respectively. The second quarter and first six months of 2018 includes net discrete income tax benefits of $3.4 million and $5.5 million, respectively. The 2018 second quarter and first six months net discrete tax benefits includes $4.7 million and $7.7 million, respectively, related to share-based accounting. The first six months of 2018 includes the first quarter $0.6 million increase in the provisional charge. The second quarter and first six months of 2017 included net discrete income tax benefits of $4.6 million and $6.0 million, respectively. The 2017 second quarter and first six months net discrete tax benefits includes an $8.1 million income tax benefit related to the release of valuation allowance for which the deferred tax assets are now determined more-likely-than-not to be realizable and $4.6 million in income tax expense related to adjustments for uncertain tax positions. The 2017 second quarter and first six months net discrete tax benefits includes $1.2 million and $2.8 million, respectively, related to share-based accounting. Excluding the net discrete income tax benefits in both periods and the increase in the provisional charge, the effective tax rates would have been 21.0% for the second quarter of 2018 and 21.3% for the first six months of 2018. Excluding net discrete income tax benefits in both 2017 periods, the effective tax rates would have been 27.4% for the second quarter and 27.7% for the first six months of 2017. The decrease in the effective tax rate in both 2018 periods, primarily reflects the lower corporate income tax rates as part of the Tax Act.

Available borrowing capacity under the $750.0 million credit facility, which is reduced by borrowings and certain outstanding letters of credit, was $674.9 million at July 1, 2018. The credit agreements require the Company to comply with various financial and operating covenants and at July 1, 2018, the Company was in compliance with these covenants.

Teledyne estimates the fair value of its long-term debt based on debt of similar type, rating and maturity and at comparable interest rates. The Company’s long-term debt is considered a level 2 fair value hierarchy and is valued based on observable market data. The estimated fair value of Teledyne’s long-term debt at July 1, 2018 and December 31, 2017, approximated the carrying value.

At July 1, 2018, the Company had $6.0 million in capital leases, of which $1.3 million is current. At December 31, 2017, the Company had $6.7 million in capital leases, of which $1.3 million was current. At July 1, 2018, Teledyne had $27.7 million in outstanding letters of credit.

For a further description of the Company’s commitments and contingencies, reference is made to Note 14 of the Company’s financial statements as of and for the fiscal year ended December 31, 2017, included in the 2017 Form 10-K.

At July 1, 2018, the Company’s reserves for environmental remediation obligations totaled $4.7 million, of which $0.6 million is included in current accrued liabilities. At December 31, 2017, the Company’s reserves for environmental remediation obligations totaled $5.1 million. The Company periodically evaluates whether it may be able to recover a portion of future costs for environmental liabilities from its insurance carriers and from third parties. The timing of expenditures depends on a number of factors that vary by site, including the nature and extent of contamination, the number of potentially responsible parties, the timing of regulatory approvals, the complexity of the investigation and remediation, and the standards for remediation. The Company expects that it will expend present accruals over many years and will complete remediation of all sites with which it has been identified in up to 30 years.

A number of other lawsuits, claims and proceedings have been or may be asserted against the Company, including those pertaining to product liability, acquisitions, patent infringement, contracts, environmental, employment and employee benefits matters. While the outcome of litigation cannot be predicted with certainty, and some of these lawsuits, claims or proceedings may be determined adversely to the Company, management does not believe that the disposition of any such pending matters is likely to have a material adverse effect on the Company’s financial statements.

Pension Plans and Postretirement Benefits

For the domestic pension plan, the discount rate decreased to 4.02% in 2018 compared with a 4.54% discount rate used in 2017. Pension expense allocated to contracts pursuant to U.S. Government Cost Accounting Standards (“CAS”) was $3.3 million and $3.5 million for the second quarter of 2018 and 2017, respectively. Pension expense allocated to contracts pursuant to U.S. Government Cost Accounting Standards (“CAS”) was $6.5 million and $6.9 million for the first six months of 2018 and 2017, respectively. Pension expense determined under CAS can generally be recovered through the pricing of products and services sold to the U.S. Government. Teledyne did not make any cash pension contributions to its domestic qualified pension plan since 2013. No cash pension contributions are planned for 2018 for the domestic qualified pension plan.

Segment Reporting [Abstract]

Segment Information

Segment Information

Teledyne is a leading provider of sophisticated instrumentation, digital imaging products and software, aerospace and defense electronics, and engineered systems. Our customers include government agencies, aerospace prime contractors, energy exploration and production companies, major industrial companies and airlines. The Company has four reportable segments: Instrumentation; Digital Imaging; Aerospace and Defense Electronics; and Engineered Systems.

Segment results include net sales and operating income by segment but excludes equity income or loss, unusual non-recurring legal matter settlements, interest income and expense, gains and losses on the disposition of assets, sublease rental income and non-revenue licensing and royalty income, domestic and foreign income taxes and corporate office expenses. Corporate expense includes various administrative expenses relating to the corporate office and certain non-operating expenses, including certain acquisition related transaction costs, not allocated to our segments.

In the second quarter of 2018, we realigned the reporting structure for certain of our microwave product groupings. These products, acquired with the acquisition of e2v were formerly reported as part of the Aerospace and Defense Electronics segment and are now reported as part of the Digital Imaging segment. Previously reported segment data has been adjusted to reflect this change. Total sales for these products were $24.2 million for fiscal year 2017.

The following table presents Teledyne’s segment disclosures (dollars in millions):

(a)

Net sales excludes inter-segment sales of $5.5 million and $10.7 million for the second quarter and first six months of 2018, respectively, and $7.5 million and $11.4 million for the second quarter and six months of 2017, respectively.

(b)

The second quarter of 2017 included pretax charges of $4.0 million in acquisition transaction costs related to the acquisition of e2v, of which, $3.7 million was recorded in the Digital Imaging segment and $0.3 million was recorded in the Aerospace and Defense Electronics segment. The first six months of 2017 includes pretax charges of $16.9 million in acquisition transaction costs related to the acquisition of e2v, of which $6.2 million was recorded in the Digital Imaging segment, $0.3 million was recorded in the Aerospace and Defense Electronics segment and $10.4 million was recorded in Corporate expense.

Identifiable assets are those assets used in the operations of the segments. Corporate assets primarily consist of cash, deferred taxes, net pension assets/liabilities and other assets (in millions):

Identifiable assets:	July 1, 2018		December 31, 2017
Instrumentation	$	1,387.1	$	1,413.6
Digital Imaging	1,593.6		1,606.5
Aerospace and Defense Electronics	519.7		495.4

Corporate	263.2		223.9
Total identifiable assets	$	3,882.9	$	3,846.4

Product Lines

The Instrumentation segment includes three product lines: Environmental Instrumentation, Marine Instrumentation and Test and Measurement Instrumentation. Teledyne’s other three segments each contain one product line.

The following tables provide a summary of the net sales by product line for the Instrumentation segment (in millions):

	Second Quarter				Six Months
Instrumentation	2018		2017		2018		2017
Marine Instrumentation	$	118.7	$	107.0	$	222.9	$	216.5

Total	$	262.6	$	233.8	$	501.6	$	466.6

We also disaggregate our revenue from contracts with customers by customer type, contract-type and geographic region for each of our segments, as we believe it best depicts how the nature, amount, timing and uncertainty of our revenue and cash flows are affected by economic factors. As we adopted Topic 606 using the modified retrospective transition method, prior period information was not adjusted for Topic 606 and comparative disclosures for disaggregated revenue are not required in the year of adoption.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis of Presentation

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements have been prepared by Teledyne Technologies Incorporated (“Teledyne” or the “Company”) pursuant to the rules and regulations of the Securities and Exchange Commission. Certain information and disclosures normally included in notes to consolidated financial statements have been condensed or omitted pursuant to such rules and regulations, but resultant disclosures are in accordance with accounting principles generally accepted in the United States (“GAAP”) as they apply to interim reporting. The condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and the related notes in Teledyne’s Annual Report on Form 10-K for the fiscal year ended December 31, 2017 (“2017 Form 10-K”).

In the opinion of Teledyne’s management, the accompanying unaudited condensed consolidated financial statements contain all adjustments (consisting of normal recurring adjustments) necessary to present fairly, in all material respects, Teledyne’s consolidated financial position as of July 1, 2018 and the consolidated results of operations, consolidated comprehensive income or the three and six months then ended and cash flows for the six months then ended. The results of operations and cash flows for the period ended July 1, 2018 are not necessarily indicative of the results of operations or cash flows to be expected for any subsequent quarter or the full fiscal year. Certain prior year amounts have been reclassified to conform to the current period presentation.

In the second quarter of 2018, we realigned the reporting structure for certain of our microwave product groupings. These products, acquired with the acquisition of e2v were formerly reported as part of the Aerospace and Defense Electronics segment and are now reported as part of the Digital Imaging segment. Previously reported segment data has been adjusted to reflect this change. Total sales for these products were $24.2 million for fiscal year 2017.

Recent Accounting Pronouncements

Recent Accounting Pronouncements

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). The new guidance will require lessees to recognize most leases on their balance sheet as a right-of-use asset and a lease liability, other than leases that meet the definition of a short-term lease. For income statement purposes, the FASB retained a dual model, requiring leases to be classified as either operating or finance. The new guidance is effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years, with early adoption permitted. The new guidance can be adopted using either a modified retrospective transition, requiring application at the beginning of the earliest comparative period presented or a transition method whereby companies could continue to apply existing lease guidance during the comparative periods and apply the new lease requirements through a cumulative-effect adjustment in the period of adoption rather than in the earliest period presented without adjusting historical financial statements. We plan to adopt the new standard on December 31, 2018, the beginning of our 2019 fiscal year, and are currently evaluating the impact this guidance will have on the consolidated financial statements, including the selection of a transition method, and footnote disclosures. Please refer to Note 13 of the Notes to Consolidated Financial Statements included in our 2017 Form 10-K for additional information about the Company’s leases, including the future minimum lease payments of the Company’s operating leases at December 31, 2017.

In February 2018, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2018-02, “Income Statement-Reporting Comprehensive Income (Topic 220) Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income”, to address a specific consequence of the Tax Cuts and Jobs Act (“Tax Act”) by allowing a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Act reduction of the U.S. federal corporate income tax rate.  The guidance is effective for all entities for annual periods beginning after December 15, 2018, with early adoption permitted, and is to be applied either in the period of adoption or retrospectively to each period in which the effect of the change in the U.S. federal corporate income tax rate in the Tax Act is recognized.   Teledyne is currently evaluating the impact this guidance will have on the consolidated financial statements and footnote disclosures.

In August 2017, the FASB issued ASU No. 2017-12, “Derivatives and Hedging (Topic 815) Targeted Improvements to Accounting for Hedging Activities.” This ASU better aligns an entity’s risk management activities and financial reporting for hedging relationships. This ASU expands and refines hedge accounting for both nonfinancial and financial risk components, and this ASU simplifies and aligns the recognition and presentation of the effects of the hedging instrument and the hedged item in the financial statements. This ASU is effective for fiscal years beginning after December 15, 2018 and for interim periods therein, with early adoption permitted. Teledyne is currently evaluating the impact this guidance will have on the consolidated financial statements and footnote disclosures.

In January 2017, the FASB issued ASU 2017-04, Simplifying the Test for Goodwill Impairment, which eliminates the computation of the implied fair value of goodwill to measure a goodwill impairment charge. Instead, entities will record a goodwill impairment charge based on the excess of a reporting unit’s carrying amount over its fair value. The new standard is effective for interim and annual reporting periods beginning after December 15, 2019, with early adoption permitted. We expect the adoption of this standard will reduce the complexity surrounding the evaluation of goodwill for impairment. The impact of this new standard for the Company will depend on the outcomes of future goodwill impairment tests.

In May 2014, the FASB issued ASU No. 2014-09 (Topic 606), Revenue from Contracts with Customers, which provides a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and superseded most current revenue recognition guidance under Topic 605, Revenue Recognition. Under the new standard, an entity recognizes revenue when or as it satisfies a performance obligation by transferring control of a good or service to the customer, either at a point in time or over time. The new standard requires expanded disclosures, including how and when we satisfy performance obligations as well as additional disaggregated revenue information to be provided more frequently in the reporting process.

In March 2017, the FASB issued ASU No. 2017-07, “Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost.” This ASU requires the service cost component of net benefit costs to be disaggregated from all other components and be reported in the same line item or items as other compensation costs and allow only the service cost component to be eligible for capitalization when applicable. The other components of net benefit cost are required to be presented in the income statement separately from the service cost component and before income from operations. The Company adopted the requirements of this ASU as of January 1, 2018 on a retrospective basis. As such, the Company reclassified $2.9 million and $0.5 million from cost of sales and selling, general and administrative expenses, respectively to non-service retirement benefit income for the three months ended July 2, 2017 and reclassified $5.7 million and $1.0 million from cost of sales and selling, general and administrative expenses, respectively to non-service retirement benefit income for the six months ended July 2, 2017 to conform to current period presentation.

The Company adopted the requirements of Topic 606 as of January 1, 2018, using the modified retrospective transition method which required a cumulative-effect adjustment as of the date of adoption. Adoption of Topic 606 primarily impacted contracts for which revenue prior to fiscal year 2018 was recognized using the percentage of completion (“POC”), units-of-delivery or milestone methods, as these contracts are now recognized primarily using the POC cost-to-cost method to depict the transfer of control of the good or service to the customer as the work on the contract is performed. Also, to a much lesser extent, certain contracts for customized goods and services, certain products sold to the U.S. Government, and product repair contracts are now recognized over time, as control of the good or service produced transfers to the customer over time in accordance with the guidance in Topic 606. For impacted contracts that were in process at December 31, 2017, we calculated the difference in the life to date revenue (and related costs and expenses) between legacy accounting standards and Topic 606, with the cumulative effect of initially applying Topic 606 as an adjustment to the opening balance of retained earnings, as shown below. The prior year comparative information has not been restated and continues to be reported under the accounting standards in effect for those periods. While Topic 606 includes additional disclosures, as discussed within these Notes to the Condensed Consolidated Financial Statements, comparative disclosures with prior periods are not required in the year of adoption due to our use of the modified retrospective transition method.

The cumulative effect of the changes made to our consolidated January 1, 2018 balance sheet for the adoption ofTopic 606 were as follows (in millions):

	Balance at December 31, 2017		Topic ASC 606 Adjustments		Balance at January 1, 2018

Significant Accounting Policies Update

Our significant accounting policies are detailed in “Note 2: Summary of Significant Accounting Policies” of our Annual Report on Form 10-K for the year ended December 31, 2017. Significant changes to our accounting policies as a result of adopting Topic 606 are discussed below.

Revenue Recognition

We determine the appropriate method by which we recognize revenue by analyzing the nature of the products or services being provided as well as the terms and conditions of contracts or arrangements entered into with our customers. We account for a contract when it has approval and commitment from both parties, the rights of the parties are identified, payment terms are identified, the contract has commercial substance and collectability of consideration is probable. A contract’s transaction price is allocated to each distinct good or service (i.e., performance obligation) identified in the contract, and each performance obligation is valued based on its estimated relative standalone selling price. For standard products or services, list prices generally represent the standalone selling price. For performance obligations where list price is not available, we typically use the expected cost plus a margin approach to estimate the standalone selling price for that performance obligation. Approximately 60% of our revenue is recognized at a point in time, with the remaining 40% recognized over time.

Revenue recognized at a point in time relates primarily to the sale of standard or minimally customized products, with control transferring to the customer generally upon the transfer of title. This type of revenue arrangement is typical for our commercial contracts within the Instrumentation, Digital Imaging, and Aerospace and Defense Electronics segments, and to a lesser extent for certain commercial contracts within the Engineered Systems segment relating to the sale of standard hydrogen/oxygen gas generators. In limited circumstances, customer specified acceptance criteria exist. If we cannot objectively demonstrate that the product meets those specifications prior to the shipment, the revenue is deferred until customer acceptance is obtained. Performance obligations recognized at a point in time can include variable consideration, such as product returns and sales allowances. The estimation of this variable consideration and determination of whether to include estimated amounts as a reduction in the transaction price is based largely on an assessment of our anticipated performance and all information (historical, current and forecasted) that is reasonably available to us.

Revenue recognized over time relates primarily to contracts to design, develop and/or manufacture highly engineered products used in both defense and commercial applications. This type of revenue arrangement is typical of our U.S. government contracts and to a lesser extent for certain commercial contracts, with both contract types occurring across all segments. The customer typically controls the work in process as evidenced either by contractual termination clauses or by our right to payment for costs incurred to date plus a reasonable profit for products or services that do not have an alternative use. As control transfers continuously over time on these contracts, revenue is recognized based on the extent of progress towards completion of the performance obligation. The selection of the method to measure progress towards completion requires judgment and is based on the nature of the products or services to be provided. We generally use the cost-to-cost measure of progress as this measure best depicts the transfer of control to the customer which occurs as we incur costs on our contracts. Under the cost-to-cost method, the extent of progress towards completion is measured based on the ratio of costs incurred to date to the total estimated costs at completion of the performance obligation. The transaction price in these arrangements may include estimated amounts of variable consideration, including award fees, incentive fees, or other provisions that can either increase or decrease the transaction price. We estimate variable consideration at the amount to which we expect to be entitled, and we include estimated amounts in the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur when the estimation uncertainty is resolved. The estimation of this variable consideration and determination of whether to include estimated amounts in the transaction price are based largely on an assessment of our anticipated performance and all information (historical, current and forecasted) that is reasonably available to us.

The majority of our over time contracts have a single performance obligation as the promise to transfer the individual goods or services is not separately identifiable from other promises in the contracts and, therefore, not distinct. Over time contracts are often modified to account for changes in contract specifications and requirements. We consider contract modifications to exist when the modification either creates new or changes the existing enforceable rights and obligations. Most of our contract modifications on over time contracts are for goods or services that are not distinct from the existing contract due to the significant integration service provided in the context of the contract and are accounted for as if they were part of that existing contract. The effect of a contract modification on the transaction price and our measure of progress for the performance obligation to which it relates, is recognized as an adjustment to revenue (either as an increase in or a reduction of revenue) on a cumulative catch-up basis.

For over time contracts using cost-to-cost, we have an Estimate at Completion (“EAC”) process in which management reviews the progress and execution of our performance obligations. This EAC process requires management judgment relative to assessing risks, estimating contract revenue and cost, and making assumptions for schedule and technical issues. This EAC process requires management’s judgment to make reasonably dependable cost estimates. Since certain contracts extend over a longer period of time, the impact of revisions in cost and revenue estimates during the progress of work may adjust the current period earnings through a cumulative catch-up basis. This method recognizes, in the current period, the cumulative effect of the changes on current and prior quarters. Additionally, if the current contract estimate indicates a loss, a provision is made for the total anticipated loss in the period that it becomes evident. Contract cost and revenue estimates for significant contracts are generally reviewed and reassessed quarterly. The majority of revenue recognized over time uses an EAC process. The net aggregate effects of these changes in estimates on contracts accounted for under the cost-to-cost method in the first six months of 2018 was less than $0.1 million of unfavorable revenue and operating income. None of the effects of changes in estimates on any individual contract were material to the condensed consolidated statements of income for any period presented.

While extended or non-customary warranties do not represent a significant portion of our revenue, we recognize warranty services as a separate performance obligations when it is material to the contract. When extended or non-customary warranties represents a separate performance obligation, the revenue is deferred and recognized ratably over the extended warranty period.

The timing of revenue recognition, billings and cash collections results in billed accounts receivable, unbilled receivables (contract assets), and customer advances and deposits (contract liabilities, which are included in accrued liabilities and other long-term liabilities) on the Condensed Consolidated Balance Sheet. Under the typical payment terms of our over time contracts, the customer pays us either performance-based payments or progress payments. Amounts billed and due from our customers are classified as receivables on the Condensed Consolidated Balance Sheet. We may receive interim payments as work progresses, although for some contracts, we may be entitled to receive an advance payment. We recognize a liability for these interim and advance payments in excess of revenue recognized and present it as a contract liability which is included within accrued liabilities and other long-term liabilities on the Condensed Consolidated Balance Sheet, which represented $101.6 million and $14.0 million as of July 1, 2018, and $110.3 million and $15.5 million as of January 1, 2018, respectively. Contract liabilities typically are not considered a significant financing component because these cash advances are used to meet working capital demands that can be higher in the early stages of a contract, and these cash advances protect us from the other party failing to adequately complete some or all of its obligations under the contract. When revenue recognized exceeds the amount billed to the customer, we record an unbilled receivable (contract asset) for the amount we are entitled to receive based on our enforceable right to payment. The unbilled receivable balance increased from the beginning of the year by $36.5 million, or 30.7%, primarily due to work performed ahead of billings on certain over time revenue contracts primarily in our Aerospace and Defense Electronics operating segment. Contract liabilities decreased from the beginning of the year by $10.3 million, or 8.1%, primarily due to the recognition of revenue in the year on customer advances that existed at the beginning of the year. The Company recognized revenue of $48.6 million during the quarter ended July 1, 2018 from contract liabilities that existed at the beginning of year. The Company recognizes the incremental costs of obtaining or fulfilling a contract as expense when incurred if the amortization period of the asset is one year or less. Incremental costs to obtain or fulfill contracts with an amortization period greater than one year were not material.

Remaining performance obligations represent the transaction price of firm orders for which work has not been performed as of the period end date and excludes unexercised contract options and potential orders under ordering-type contracts (e.g., indefinite-delivery, indefinite-quantity). As of July 1, 2018, the aggregate amount of the transaction price allocated to remaining performance obligations was $1,632.6 million. The Company expects approximately 83% of remaining performance obligations to be recognized into revenue within the next twelve months, with the remaining 17% recognized thereafter.
